Steel plate shear walls usually do not satisfy the strong-column weak-beam design criteria, leading to larger column sections. On other hand, rigid frame structures are typically constructed in low-rise mid-rise buildings built locations prone strong earthquakes due their high flexibility and cost-effective solutions. Overcoming these restrictions SPSW system, this paper is dedicated employing ...

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...

This paper is an experimental study on the behavior of vertical shear link in the single and double configurations. There have been three specimens selected for examining the effects of different details .The first specimen was an I section with no stiffener, while the second specimen composed of I section with stiffeners designed according to AISC 2005. Third specimens were composed of two I s...

The objective of this paper is to describe and analyze a series of nonlinear finite element analyses used to compare three design methods for locally slender, braced, steel beams and columns. The three design methods are: (i) the hot-rolled steel AISC Specification, (ii) the coldformed steel AISI Specification which uses the effective width method throughout, and (iii) the cold-formed steel Dir...

One of the major purposes of optimization in civil engineering is to perform a suitable design for the structure. This goal has to fulfill technical criteria and contain the minimum economical costs. Building frames are of the most customary civil engineering structures. Therefore, optimization of these types of structures could be of a great concern from the economical viewpoints. One of the c...
