Abstract:

The present work sheds light on the effects of varying frequency content (FC) of earthquake ground motions (GMs) on the behavior of three-story reinforced concrete (RC) regular frame buildings, modeled as a bare frame and soft open ground story (SOGS). It is extremely significant to know the characteristics of ground motion to avoid the vulnerability of structures. The important dynamic characteristics are peak ground acceleration (PGA), FC, and duration. Nine earthquakes with varying FC occurred earlier in different parts of the World and are performed on the building models to investigate the seismic fragility responses thoroughly. The base share calculated by equivalent static analysis (ESA) and response spectrum analysis (RSA) as per IS 1893 (Part 1): 2016 procedures, and linear time history analysis (LTHA) using ETABS 2015 are distributed along with the height of the building models. The building models' responses, namely: natural periods, base shear, roof displacement, inter-story drift, inter-story velocity, and inter-storey accelerations, and inter-storey stiffness, is also known as engineering demand parameters (EDPs), are presented. Authors conclude that the civil engineers can employ brick or concrete block infill walls in three-story RC buildings depending upon their availability and procurement cost at the construction site. There are no considerable changes in seismic responses. Additionally, the buildings built in earthquake-prone areas are analyzed with LTHA considering at least one earthquake GM with low or intermediate FC. Furthermore, all the maximum responses increase as the FC of the considered earthquakes decreases.

Keywords:
