Steel braced frames are commonly used in steel structures to control and improve the seismic performance of under severe lateral forces such as an earthquake. So, providing better formability would help designers achieve their desire level. This study is focused on utilizing curved dampers ductile frame instead using knee elements provide energy dissipation, strength, elastic stiffness during c...
the knee bracing steel frame (kbf) is a new type of energy dissipating frame which enjoys exceptional ductility and lateral stiffness. rather than the beam-column joint, one end of the diagonal brace in kbf is attached to the knee element. indeed, the knee element as a hysteretic damper is designed and detailed to behave like a structural fuse by sustaining controlled inelastic deformations as ...
INTRODUCTION Knee osteoarthritis causes debilitating pain, and results in characteristic gait changes. Some authors believe that a system of neuromuscular retraining may improve these parameters. We therefore evaluated a novel brace that combines pneumatic joint unloading and active swing-assist to assess: (1) differences in pain levels or medication usage; (2) reductions in additional interven...
steel structures are usually built with some defects. according to the standard building codes, the central axes of the bracing members should go through the beam-column joints, however, in most of the braced steel structures, bracing members are unintentionally connected eccentrically. this paper presents a numerical investigation on performance analysis of cbfs (concentrically braced frames) ...

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)...
The self-centring system presented in this paper is a novel damage control technique designed to improve the resilience of concentrically braced frames (CBF) under seismic action. Namely, traditional CBFs can undergo large residual drifts following an earthquake event which limit opportunity for cost-effective repair structure. Additionally, gusset plates connecting brace members beams and/or c...
