1. During the design, how can we show the failure members in different color? select>by spec>all failed beams

2. Explain: Translational repeat > Generation flagsAll-geom,prop,load,support,design parameters etcGeom only,geom and prop only

3. Explain: Member releaseGenerally, all fx,fy,fz,mx,my,mz is transferred to next beam via nodez, if we hav to block any of those forces separately. We hav to mention that using member release

4. Explain: Member TrussCommand>member spec> trusscant handle bending/ torsion/ shear load

5. Explain the application of BEAVA page253Traffic Lanes, critical location of udl/knife load/vehicle load, Asociated load value(influence surfaz)

6. Explain: Response SpectrumDynmic to analyse the structure for seismic loading. We calculate joint displacement.member forces and support reactions. Can use sqr root of the sum of sqrz, 10 % or absolute method to derive the result. The result along static is considered before design.load can b +ve or –ve to consider seismic reversibility.

7. Explain Surcharge for loading in isolated foundation design.8. Explain: Combined footing > Fixed left / right overhang

Left/right over hang value will be fixed or else it will be designed as per requirement

9. Explain: Mat foundation > Add Meshing RegionsMat foundation job>mesh generation>add mesh region1. Using polylines2. Add rectangular3. Add circular region4. Regular polygon

10. Wind load > Exposure(102)used to modify the influence area associated with partklr strctur joint

11. Explain: Cable memberElastic axial deformation and stiffness due to static load.command mem spec initial tension/unstressed length

12. Explain: Enforced and Inclined supports

Page 2: staad

Enforced= fixed, but for plates/solids will provide support displacementinclined offer restrains in an axis inclined with global axis. for that we need a reference point

13. Explain: Soil Subgrade modulus14. Unit for Moment of Intertia=length^415. Concrete design parameters > Width & Depth

Width=width to be used=ZD in membr prop (page 131)Depth=depth “ = YD “

16. Explain: Optimization in FEM17. Explain: Isolated foundation > Design type

2 types. Calculate dimension and set dimensionCalculate- will design the least possible size meeting the specified loads ( in the range we entered)Set dimension: one dimension is fixed and the other is designed

fixed width(length will be optimized), fixed length

18. Explain: Pile in pile cap19. Explain: Section force

(125) prints mmbr forzz at d intermediate sections provided with a previously defined command. Results are tabulated using load cases

20. Explain: Time History AnalysisAdvanced dynamic analysis. ability to incorporate harmonic forcing functions that can be described by sinusoidal with a specified arrival time , frequency and amplitude and duration.Time-history analysis provides for linear or nonlinear evaluation of dynamic structural response under loading which may vary according to the specified time function. Dynamic equilibrium equations, given by K u(t) + C d/dt u(t) + M d2/dt u(t) = r(t), are solved using either modal or direct-integration methods.
