Seismic Design

Introduction

In continuation to the article on the comparison of earthquake base shear calculation, This article integrates steps for seismic analysis of structure as per ASCE 7 and IBC.

Irregularity

Code divides irregularity under two broad headings, Horizontal and Vertical Irregularity.

Seismic Devices

For structures categorized under Seismic Design Category D to F, seismic devices offer a cost-effective design alternative. Mindmap 3

In Buildings and Structures, the use of basement pedestals (refer to Figure 1) to support base isolators further lengthens the fundamental period and reduces response ( Example Bhuj Hospital).
