What's NewThe Software Release Report for STAAD Foundation Advanced V8i contains

detailed information on new features and enhancements made to the product.Thank you for your purchase of a STAAD Foundation Advanced V8i license!This new product is built upon the previous STAAD.foundation program butincludes powerful new features and an improved user interface. The namechange represents the extended feature set available in the program incomparison to the limited foundation design capabilities which are available with a license of STAAD.Pro V8i.

Whether you are new to STAAD Foundation or have used STAAD.foundation inthe past, then we suggest you spend some time reading this document andtrying some of the examples in order to familiarize yourself with the program.Even if you've used previous versions STAAD.foundation before, we feel that you'll benefit from learning the new user interface.The following list provides describes new features for users of STAADFoundation (the previous version of this product).

General Program FeaturesThe following features have been added to the program as general features:

Ribbon interface

The user interface has been updated with a new tabbed toolbar set—oftenreferred to as a Ribbon—similar to that found in Microsoft Office 2007 andlater. This provides better organization of tools and features as well as exposesmany features which often hard to locate.

l File operations, such as creating new files, opening existing files, savingfiles, and printing are included on the Application menu, which isaccessed by click the Application menu button located in the top-leftcorner of the program window.

User Manual — 1


7/455

l All other tools are located on a series of Ribbon tabs, which are groupedby feature.

l Commonly used tools can be added to the Quick Access toolbar, which is

visible from just below the Ribbon and remain the same regardless of which Ribbon tab is selected.

Export of detailed output to Microsoft OfficeExcel® spreadsheet file

You can now export detailed output to a Microsoft Office Excel® spreadsheetfile for the following types of general foundations:

l Isolated footings (US and Indian codes)l

Combined footings (US and Indian code)l Strap foundations (US code Only)l Octagonal foundations (US Code only)

From the Footing job branch in the Main Navigator pane, select the DetailedOutput option. A Windows Save As dialog opens to save the detailed designinformation for each footing in the current job to an .XML file in the ExcelXML format, which can then be opened in Microsoft Office Excel.

Drilled/Driven Pier foundations

A new parametric wizard has been added to design drilled shaft or driven pierfoundations used to resist axial and lateral loads. The pier can have any number of sections along its length and essentially any number of soil layerscan be modeled.



10/455

What's New

Group Horizontal Vessel Footings

The foundations at each end of a Heat Exchanger/Horizontal Vessel foundationcan be designed as identical. This option will then only allow input for the

"Left" Footing and design both foundations for the maximum requirements.Simply set the Identical Footings option on the Footing Geometry page when Isolated Footings are being designed.

Self Weight for Ultimate Loads

The option to include the foundation self weight for ultimate loads (concretedesign) under the Global Settings dialog box is now respected for Plantfoundation jobs as well as foundation jobs created under the Generalfoundation mode.Simply click the Global Options tool found on the Home ribbon tab and setthe option.

General ModeThe following features have been added to the General foundation mode inSTAAD Foundation:

User Manual — 5


11/455

Octagonal Footing

An isolated, octagonal footing—similar to the option for the Vertical Vessel inPlant mode—can be designed as a separate foundation job from the General

mode. Parameters similar to other isolated footings are entered via property pane, as well as anchor bolt data for concrete design.This foundation types can be selected when creating a new foundation job inthe General mode for US code design.

Strap Footing

A strap footing—similar to the option for Heat Exchanger/Horizontal Vesselin Plant mode—can be designed as a separate foundation job in the Generalmode. This foundation type consists of a grade beam between two isolated

footings. This single job analyzes the beam and footing system and designs both elements.This foundation types can be selected when creating a new foundation job inthe General mode for US code design.

Australian Code Modification

Several enhancements have been made to the design of foundations per the Australian code:

l Strength reduction factor, φ, from table 2.3: one-way shear, punchingshear, and reinforcement

l Modified punching shear calculations per Sect. 9.2l Refined minimum percent of steell A revised calculation sheet

Section 1

Getting Started1.1 Welcome

Thank you for your purchase of STAAD Foundation Advanced V8i. STAADFoundation is an exhaustive analysis, design, and drafting solution for a variety of foundations. These include general foundation types such as isolated,combined footings, mat foundations, pile caps, slab on grade, octagonal, strap,and slab on piles as well as plant foundation such as vertical vessel and heatexchanger foundations. A part of the STAAD family of products, STAADFoundation can automatically import and update the geometry, loads, andreactions from a STAAD.Pro model and then accurately design isolated, pilecap, combined footing, mat, octagonal, and strap foundations and even performpile arrangements for a pile cap. Spreadsheet data (e.g., such as that inMicrosoft Office Excel®) can be copied and then pasted in STAAD Foundation,increasing the efficiency and versatility of the program.STAAD Foundation not only analyzes and designs a myriad of foundationconfigurations, but will also produce production quality reports and detailed3D rendering of your foundation structures. It also produces site-ready construction documents such as: detail drawings, general arrangementdrawings, and schedule drawings. With full OpenGL graphics, engineers can

clearly see the displaced shape, stress distribution, reinforcement layout, andforce diagrams of their supporting structure. All models use physical objectsincluding physical beams, physical slabs, automatic meshing, loaddistributions, and support generation. STAAD Foundation designs the physicalslabs rather than individual elements.For mat foundation designs, STAAD Foundation utilizes a true finite elementdesign using the individual element stresses rather than using column strips.STAAD Foundation can be used in a stand-alone mode or can be used inconjunction with STAAD.Pro where the support reactions from the mainmodel and associated load cases are automatically brought in.Because STAAD Foundation provides a total solution for your foundationneeds, a built-in project management system enables line and span of control,revision records and multi-job functionalities. This helps you reduce cost inassembling the technical and managerial information for your foundation. Full

step-by-step calculations are also provided in XML form to verify each andevery output provided by the program. These verification checks can be easily shared with your clients for approval. Also, the calculation sheets can be customized according user specification andentire foundation reporting can be standardized.

We hope you enjoy your experience with STAAD Foundation. If you have any questions or problems with the program, please visit our product page athttp://www.bentley.com/en-US/Products/Staad.foundation .

1.2.3 Foundation ModesSTAAD Foundation can operation in three different modes, depending on thetype of foundation you want to model, analyze, and design. You will select one

of these modes when creating your project:l General Foundation - Open modeling of common foundation types.l Plant Foundation - Parametric modeling wizards for common foun-

dations used in plant environments.l Foundation Toolkit - Parametric modeling wizards for common foun-

dation types.

1.2.4 Global and Local dataIn STAAD Foundation, you start out by creating a Project to hold all yourphysical information, such as column locations, loads, etc. This physicalinfor mation rep resents the structure that the foundation is intended tosupport. Unle ss the design of the structure is modified, these physicalconditio ns generally remain constant throughout the life of the foundationdesign project. Your Project also contains Jobs, which are sets of constraints needed to tellthe program how to perform a foundation design. Each job contains the localdata for that specific foundation configuration. A job may represent separatefoundation type which coexist on the same structure, several differentfoundation scenarios used to evaluate different solutions, or even differentstages of construction. It is a flexible system but one that allows you toorganize the project to meet your needs.The current job being evaluated can be selected using the Active Job drop-down found in the Standard Toolbar.

Note: STAAD Foundation consists of two sets of data, global and local.Global data such as column reactions and column positions is sharedthroughout a project among both similar and different jobs. Local datasuch as design parameters is used only within a specific job type. For

example, an Isolated Footing job type has local data within the designparameters group. A project may contain multiple jobs, making it easy for you to evaluate different design scenarios for a given set of physicalconditions.

Top Reinforcement OptionSelect to Always Calculate Top Reinforcement Based on Concrete andSoil Weight or to Calculate Top Reinforcement Only When Foundation isSubjected to Uplift Forces. The first option will always include topreinforcement, where as the latter will omit it if the calculations indicateit is not necessary due to applied forces.

Ultimate Check Self weight OptionSelect this option to include the self weight of the footing, along withsoil dead weight and buoyancy effect in concrete design check. Thisoption is particularly useful when footing loses contact with the soil(uplift condition), as the concrete design tends to be very nonconservative without consideration of self weight.

Section 2

General Foundations2.1 Introduction

In STAAD Foundation, you start out by creating a Project to hold physicalinformation, such as column locations, column dimensions, piles, beams, andloads. The physical information represents the structure that a foundation isintended to support. Unless the design of the structure is modified, thesephysical conditions generally remain constant throughout the life of afoundation design project. Your project also contains Jobs, which are sets of constraints needed to tell STAAD Foundation how to perform a foundationdesign. Each project may contain multiple jobs, making it easy for you toevaluate different design scenarios for a given set of physical conditions.

Note: STAAD Foundation does not display the entire tree all the time.Rather, it only displays groups and leaves that are relevant to the currentstatus of the project. For example, when you begin a new project, only theProject Info, Foundation Plan, Loads and Factors and Job Setup groups willappear in the Navigator pane. These four groups allow you to specify thephysical model upon which the foundation design is performed. It is only when you specify a Job (a set of constraints for STAAD Foundation to use

User Manual — 71


77/455

in performing a foundation design) that the groups related to the design will appear.

2.2 Global DataThe main navigator pane Global Data groups are as follows:

2.2.1 Project InfoUsed to add general info about a project, create a revision history for aproject, and access view and scaling controls. The Project Info group is active by default when you open a new or existing project.Use of the Project Info group is optional. It is provided for your convenience. You can store relevant general information regarding a project and also createa revision history. Later on, you can instruct STAAD Foundation to display this information in reports and drawings.
