Abstract The Mega-Sub Controlled Structure System (MSCSS) is a new type of seismic structural system. This research aims to find weak members in the structure and better describe failure state. To achieve this, we enhanced story drift ratio indicator by combining it with path proposed comprehensive that can more accurately behavior structure. concept proposed. waves used analysis this article a...

The experience of past prominent earthquakes establishes the fact that the structure’s catastrophes and casualties can be dramatically decreased through the use of self-centering systems. A promising post-tensioned self-centering yielding braced system (PT-SCYBS) has been developed, comprising of two main components, including the post-tensioned wires, exhibiting the desirable self-centering pr...

In recent years, destructive earthquakes have shown the deficiencies of the existing buildings. One of the most effective mechanisms for dissipating the earthquake energy is inelastic deformation of the steel components. The objective of this research is to study the application of metallic dampers for dissipation of the earthquake energy and to investigate the behavior of concrete structures i...

A method is presented for extracting features of approximate optimal brace types and locations large-scale steel building frames. The frame subjected to static seismic loads, the maximum stress in members minimized under constraints on number braces each story interstory drift angle. new formulation important from machine learning results using a support vector with radial basis function kernel...

During strong earthquakes, structural damage usually occurs, resulting in a degradation of the overall stiffness affected structures. This produces modification dynamic properties structures, for instance, fundamental period vibration (T1). Hence, variation T1 could be used as an indicator seismic damage. In this article, assessment four generic typologies steel buildings was carried focused on...

The seismic evaluation of existing buildings is a more troublesome assignment than the design new buildings. need for becomes necessary to know level structural damage and how cure it due earthquakes. shows structure’s behavior under loads determines ultimate capacity structure, there are several methods used in assessment analysis which may be static or dynamic. In this study, an educational b...

In this study, the effect of deep excavation on the seismic response of RC moment resisting building systems has been studied. Deep excavation can cause significant changes in the stress and strain levels of soil environment and also changes in the propagation of seismic waves. This leads to permanent displacements in the foundation system. In this study, three RC building systems, i.e. 5, 10, ...

This paper investigates the applicabilty of an innovative bracing, called Articulated Quadrilateral (AQ) bracing system, which uses shape memory alloys (SMAs), for retroffiting low-rise to high-rise vulnerable SMFRs against strong ground motions. The paper investigates brace fundamental engineering characteristics, design of the system and also configuration of the brace (the proportion of SMA ...
