2. “COMPUTER IS A DUMB MACHINE” Is it true ?
Present generation computers!!!!!
we must know two things
The language which it can understand properly
The expected outcome of command which can be validated
Correct input in proper format will only fetch a correct solution
3. MODELING Inputs
Material properties, Equilibrium and Compatibility Equations, Energy and Work Principals, Incompatible Elements, Boundary Conditions, Analysis Methods, Design Principal and Philosophy
Information about building and site condition
Number of frames with spacing of columns
Longitudinal direction
Transverse direction
Number of stories and type of diaphragm
Usage of building
Soil condition, Seismicity condition, Wind
4. LOAD CALCULATION Dead Load ? IS 875-1978 (Part-1)
Imposed Load (Live) ? IS 875-1978 (Part-2)
Earthquake ? IS 1893-2002 (Part-1)
Wind load, Snow load and other loads should be calculated based on relevant codal provisions
12. LOAD COMBINATION 1.5 (DL + IL)
1.2 (DL + IL ± EL)
1.5 ( DL ± EL)
0.9 DL ± 1.5 EL
13. Simplified Nonlinear Analysis Salient Points
Determination of capacities beyond elastic limit
Pushover procedure is used to determine capacity
Capacity spectrum method and Displacement coefficient method are used to determine performance point (ATC 40)
Performance point – The point of intersection of capacity spectrum and demand spectrum
