Adding steel braces to reinforced concrete frames is a common way for seismic rehabilitation of these structures. Due to ease of installation and the possibility of creating openings in the braced bays, this method of rehabilitation has been more preferred than using shear walls. In this paper, three experimental specimens including a reinforced concrete frame, a reinforced concrete frame with ...

Passive control methods can be utilized to build earthquake resistant structures, and also to strengthen the vulnerable ones. In this paper, we studied the effect of this system in increasing the ductility and energy dissipation and also modeled the behavior of this type of eccentric bracing, and compared the hysteresis diagram of the modeled samples with the laboratory samples. We studied seve...

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) ...

Building structures are subject to displacement under the influence of forces resulting from earthquake. The most common method of controlling such displacements in steel structures, which are usually of lateral type, is the use of braces. Depending on designing requirements and feasibility, braces are available in various forms. Configuration of bracing systems is generally of concentric or ec...

OBJECTIVE This case study was conducted to evaluate the conservative management of a patient presenting with right sided wrist and thumb pain diagnosed as De Quervain's tenosynovitis/tendinopathy. CLINICAL FEATURES A 49-year-old female warehouse worker and recreational cyclist with right-sided De Quervain's tenosynovitis/tendinopathy that began after a long-distance cycling trip. INTERVENTI...

Indonesia, which has tectonic conditions in the form of a large meeting point world's plates and several small plates, makes region Indonesia center earthquake occurrences earthquake-resistant buildings are an absolute necessity. Eccentrically Braced Frames (EBFs) model steel building structures that can limit inelastic behavior only to link elements, where use these links, especially replaceab...

OBJECTIVE Chronic tendon pathology is a soft tissue condition commonly seen in chiropractic practice. Tendonitis, tendinosis, and tendinopathy are terms used to describe this clinical entity. The purpose of this article is to review interventions commonly used by doctors of chiropractic when treating tendinopathy. METHODS The Scientific Commission of the Council on Chiropractic Guidelines and...

Abstract The ways of designing and building steel girder bridges with a composite concrete deck vary much between different parts the world. A bridge system twin I‐girders or concept multiple (more than two) girders can be used. design use details secondary systems also lot. In order to give horizontal stabilization distribute loads, bracing bracings are often Although not so common, used verti...

Configuration and geometry of bracing systems affect the seismic performance of structures significantly. Recently, the current authors have introduced a new configuration for eccentric bracing of structural frames that may be assumed as the combination of inverted Y-type and rotated K-type EBFs. The resulted braced frame is called EBF-DVL, consisting of two vertical links attached together by ...
