Historically, the seismic performance of structures with conditions of structural irregularity
has been poor in strong earthquakes when compared to those of regular structures. In …

Sequential ground motions can significantly affect the seismic demands of reinforced
concrete (RC) frames with irregularity along the height. In this paper, the effect of sequential …

Abstract Near-fault (NF) pulse-like ground motions may contain long-period velocity pulses
and high-frequency acceleration records, which impose significant damage on structures …

Near-fault (NF) ground motions may induce higher demands on structures compared to far-
fault records. This is often due to the velocity pulses, called forward-directivity pulses, which …

Background Seismic analysis of structures is required for the design of high-rise building as
these are hazards that threat the built environment and human life. However, it was …

This paper investigates the role of soil-structure interaction (SSI) in the confidence levels of
setback steel moment-resisting frames (MRFs) for meeting the structural performance …

To prevent the vertically irregular structure with setbacks from unfavorable weak-story failure
mode in major earthquakes, an upgrade optimization method for installing the buckling …

It is well understood that the dominant approach in the seismic design of structures is to
reduce the initial cost while meeting the required safety level, as dictated by compliance …

Pushover analysis technique is a key tool for the performance-based seismic design that
has been largely adopted in the new generation of seismic codes. Therefore, more precise …

Nonlinear time history analysis is an analytical method generally used in performance-
based seismic design. With this method, seismic responses are obtained more realistically …
