CHAMPION HEIGHTS COMMERCIAL BUILDING

Purpose:The goal of our project is to design a commercial building to meet the needs for the growing community of Boerne, TX.

Scope:• Design of 63,000sf concrete building• Drainage and Detention study• Onsite Parking Area, Drainage, Water, Sewer

Improvements• Offsite Streets, Drainage, Water, and Sanitary Extension

Improvements.• Construction Documents

LOADS AND ANALYSIS

• Loads Considered:• Dead• Live• Wind

• Code used:• ASCE 7-10

• Drawings done with:• AutoCAD Civil 3D 2011• Google SketchUp

• Analysis done with:• SAP2000 15

• Rain• Snow• Seismic

Ryan Krause

ENVIRONMENTAL

• Must Follow Texas Commission on Environmental Quality Guidelines • Minimal Tree Removal • No Indications of

Hazardous Materials or any Area of Contamination

Randy Rodriguez

GREEN DESIGN Green Building Materials:

• 10% Fly Ash incorporated into foundation• Use of Local Materials encouraged• Contractors must provide construction

waste management plan Optional Roof Garden:

• Native Drought resistant Plants to absorb CO2

Energy Efficient Appliances:• Low Flow Toilets• Low Flow Faucets• Waterless Urinals• LED Lighting W/ Motion SENSORS• Up to 30% in energy & water

savings expected!

FOUNDATION ANALYSIS

12345678

• Divide foundation layout into 8 strips • Analyze each strip for the shear & moment developed by the line of column loads

FOUNDATION ANALYSISDetermine: Effective depth of Shear Prism for

diagonal tension shear

Maximum Positive & Negative Moments (Interior & Exterior)

Steel reinforcement

@ pu(max)=577.55 Kips; D=20”

(+) Interior = 1269.97 k-ft(-) Interior = 186.05 k-ft(+) Exterior = 958.21 k-ft(-) Exterior = 109.75 k-ft

• Conventional Grade 60 Rebar

FOUNDATION DESIGN Foundation Type Selected:

BEAM & SLAB Foundation (Slab is suspended)!

WHY?• Simple Economics:

Less Steel+Less ConcreteSavings!

• Rigid Design• Reduction in Differential

Settlement

• High F.S.

• Eases Construction

• Floor slab is entirely isolated from expansive soils Horacio Montejano

STRUCTURAL OVERVIEWOffice Building 3-Stories:• Concrete Structure• Decking (One-Way Joist 2’ Module)• Braced Frame (CMU Walls)
