Seismic responses of unsymmetric-plan tall buildings are substantially influenced by the effects of higher modes and torsion. Considering these effects, in this article, the consecutive modal pushover (CMP) procedure is extended to estimate the seismic demands of one-way unsymmetric-plan tall buildings.

Hollow RC bridge piers exhibit several failure modes when subjected to extensive time varying loads during their service lives. Shear failure of hollow RC bridge piers is very critical as it is brittle in nature involving rapid deterioration of strength with increasing widths of the shear cracks and low ductility.

Beam-column joints are the key structural elements, which dictate the behavior of structures subjected to earthquake loading. Though large experimental work has been conducted in the past, still various issues regarding the post-yield behavior, ductility and failure modes of the joints make it a highly important research topic.

Seismic Assessment of RC Frame Structure by Nonlinear Static Pushover Analysis.
International Journal of Research and Scientific InnovationBangladesh is located in a seismically active area, and the rising number of earthquakes has alarmed the local population. Major cities of Bangladesh are under a serious threat due to defective design and structural construction. If seismic do not take under consideration building could be severely damaged under seismic loads.

In a fixed connection of a reinforced concrete bridge column, experiments have shown that the longitudinal reinforcing bars slip at the interface of the connection under cyclic seismic loading. The bond-slip (or strain penetration) of the longitudinal reinforcing bars causes a pinching effect in the column’s hysteresis curve.

AbstractThe nonlinear static pushover analysis technique is mostly used in the performance‐based design of structures. However, the pushover analysis with load distributions of Federal Emergency Management Agency (FEMA) loses its accuracy in estimating the seismic responses of long‐period structures where higher mode effects are important.

A fast converging and fairly accurate nonlinear simulation method to assess the behavior of reinforced concrete columns subjected to static-oriented pushover force and axial loading (sections under biaxial-bending moment and axial loading) is proposed. In the proposed method, the sections of column are discretized into “Variable Oblique Finite Elements”

Seismic retrofitting of already constructed buildings is one of the most effective methods of decreasing the risk. However the seismic performance of the structure may not be improved by Strengthening unless the professional engineer selects an appropriate modifying technique based on seismic evaluation of the already constructed structures.
