Spacious experimental and numerical investigation has been conducted by researchers to increase the ductility and energy dissipation of concentrically braced frames. One of the most widely used strategies for increasing ductility and energy dissiption, is the use of energy-absorbing systems. In this regard, the cyclic behavior of a chevron bracing frame system equipped with multi-pipe dampers (...
This paper presents a new approach to the project of steel buildings, mainly focused on architectural, structural, and seismic design stairs. The objective is structural stair system capable controlling damage contributing bracing building. article begins with review standard (ATC, FEMA, EC8) which current criteria for buildings stairs are based. research based two spatial building models (A–B)...
In this work, analytical pushover curves for concentric braced steel frames with active tension diagonal bracings (X-CBF) are proposed. A “spindle”, characterized by two trilinear capacity defined an X-CBF system subjected to prefixed lateral forces distribution, is defined. The able grasp the elasto-plastic behavior of X-CBFs. reliability proposal verified a series numerical comparisons obtain...
Abstract According to the AISC Seismic Provisions for Structural Steel Buildings (AISC341‐16) and EC8, inelastic rotation demand at design story drift is limited 0.08 rad I‐shape shear links in eccentrically braced frames (EBFs). Numerical studies on EBF archetypes show that single‐sided demands can be much higher than limiting value. In addition, these fail due low‐cycle fatigue (LCF) which de...
