The design response spectrum provides a general procedure to estimate the expected dynamic load on a structure which is expressed as a function of natural period. Thus knowing the period of the structure, design load could be calculated. It well known that the deterministic (DSHA) and probabilistic (PSHA) seismic hazard maps provide prediction of peak ground acceleration and ground motions for a specific site. As per NEHRP guidelines, design response spectrum is developed from the PSHA framework. The 2% pr 10% probability hazard level can be used for development of design response spectra which is actually satisfying a MCE level condition.
The accuracy in determination of PSA is very important in calculating the final shear load. Could you explain how to estimate such value for a given site?
How to calculate spectral acceleration (design acceleration) for the each type of site class?.
If you use MCE seismic hazard map you can use ASCE code to develop the design spectrum. Please check ASCE code 7-10
Dear Lalu,
Thank you for your kind reply. Please add and an explanation if you like.
I need the procedures starting from hazard map whatever is it till drawing response spectrum.
Neeraj Pandey There are various ways to scale. you can review Fema P-695.
