When structures are subjected to strong ground motion excitations, structural elements may be prone to yielding, and consequently experience significant levels of inelastic behavior. The effects of inelastic behavior on the distribution of peak floor loads are not explicitly accounted for in current seismic code procedures. During recent years, many studies have been conducted to develop new de...

The objective of this review to be submitted in two independent parts, for steel frames and for RC frames, is to compare their structural performance with respect to the proposed N2-method, and so also of the consequent convenience of using pushover methodology for the seismic analysis of these structures. A preliminary investigation is presented on a pushover analysis used for the seismic perf...

Elevated water tanks supported by the reinforced concrete (RC) Staging are classified as inverted pendulum structures. These are considered as structures of high post-earthquake importance and should remain functional after the seismic events. National codes of various countries recommend Force-Based Design (FBD) procedure for water tank staging, which does not ensure nonlinear performance leve...

the most conventional method for lateral bracing of steel frames is using diagonal and x steel braces. in conventional method, braces of frame emplace in one bay or more, relative to structural requirement, from first to last story without displace the braces emplacement on height as columnar form. this pattern is a preliminary and simplest bracing template that the generally codes present base...

In order to improve the force performance of traditional anti-buckling energy dissipation bracing with excessive non-recoverable deformation caused by strong seismic action, this paper presents a prestress-braced frame structure system shape memory alloy (SMA) and investigates its characteristics under horizontal load. Firstly, establishes theoretical analysis model analyzing geometric relation...

Performance coefficients are widely used in seismic design codes to achieve performance objectives. The values of these have significant importance achieving pre-specified goals. Studies shown that near-fault earthquakes decrease the ductility and increase risk failure structures; however, current use same structures against near- far-fault records. In present study, 1-, 5-, 10- 15-story specia...

Semi-rigid design represents, by its intrinsic nature, a new option aimed at improving the competitiveness of steel construction. This objective can be achieved via Knowledge-Based approaches. In the perspective of design automation, our research proposes a novel methodology for the detailed analysis of a braced building frame adopting semi-rigid steel joints. A software tool was developed in o...
