Dual systems of steel moment frame and reinforced concrete shear wall have combined the advantages of steel frames and reinforced concrete shear wall. These walls have increased the lateral stiffness of steel frames and have reduced seismic demands on steel frames thus providing opportunities to use such system. In this research intermediate dual system of steel moment frame was chosen with int...

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) ...

Steel braced frame systems (SBFs) having high stiffness and strength are commonly utilized due to their resistance lateral seismic forces in regions with seismicity. In this study, concentrically frames (CBFs) different bracing configurations used obtain the significance of pulse period associated near-fault (NF) ground motion by time-history dynamic analysis. Besides, far-fault (FF) motions al...

INTRODUCTION Valgus knee braces are effective at decreasing pain and improving function in patients with knee osteoarthritis (OA) [1]. The braces are designed to decrease loading in the medial knee compartment but previous studies are unclear if this truly occurs. Alternatively, changes in the neuromuscular system might account for the benefits of bracing. An earlier study with a small sample d...

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 (...

Anterior cruciate ligament (ACL) injuries most commonly occur during sports that involve sudden stops and changes in direction, such as basketball, soccer, tennis, and volleyball. Depending on the severity of the ACL injury, treatment may include surgery to replace the torn ligament followed by rehabilitation exercises to help the patient regain strength and stability. However, controversy exis...

The cold formed steel section are increasingly used as a structural elements in low rise buildings recent times, due to the advantages like economic production, easy transportation, labor cost and high strength weight ratio. In current work G+3 storied building frame is studied for seismic wind load using Staad-pro software. Light gauge taken beam slab elements. analysis carried out by Equivale...

Abstract This study investigates the seismic performance of a composite structure comprising cold-formed steel and high-strength concrete. Four short shear walls composed concrete, namely, one specimen without diagonal bracing, with angle-steel two lattice were designed for testing their low cyclic loading. The cracking load, ultimate displacement, maximum horizontal bearing capacity, failure p...

Many historical events have shown that, after an earthquake, fire may be triggered by seismic-induced rupture of gas piping, failure electrical systems, etc. The current engineering design methods still ignores many aspects multi-hazard and in particular following earthquake (FFE) analysis. In this respect, the aim paper is to study behaviour a braced steel frame subjected fire. particular, FFE...
