In this post, I will go over the first seismic design example in our seismic design of structures course covering the calculation of seismic forces. The goal of this structural seismic design example is to calculate the seismic design force and seismic base shear for a reinforced concrete building structure. We will use the equivalent…

In this post, I will provide a step-by-step summary of the equivalent lateral force procedure for the seismic design of structures. The first step is to determine the seismic design category and choose the proper seismic importance factor, IE, of the structure. The second step is to choose the appropriate response modification factor…

The basic premise behind seismic analysis of structures is to convert the earthquake dynamic forces acting on the structure to equivalent static forces which are then used as inputs in a static structural analysis to obtain the internal forces, stresses, and deformations in the structure. There are two analysis procedures described in the International Building…

The first step is to identify the risk category of the structure per International Building Code (IBC 2012), Section 1604.5. The second step is to determine the mapped maximum considered earthquake spectral response acceleration for short periods, SS, from International Building Code (IBC 2012), Figure 1613.3.1(1). The third step is to determine the…
