experimental tests were performed to study the seismic behavior and performance ofmodified steel chevron braced frame systems, which incorporate a vertical slotted connection(vsc) detail between the top of the braces and the floor beam above. the vsc detail isintended to prevent vertical load transfer to the beam and limit brace forces to thecompressive resistance of the members. full-scale qua...

One of the main parts in planning reinforced concrete structures lies beam column joint (BCJ) connection . The beam-column consists interior, exterior, and knee joints. In this study an analysis has been carried out regarding behavior joints on exterior look for capacity structural strength using conventional methods. type component will be based results laboratory test modifying data search ob...

This article considers the seismic behavior of beam-to-column joints in steel frames for different bolt arrangements by using of finite element modeling. As the most important beam-to-column joint type, the beam-to-column joints with end-plate is chosen for the analysis. Four different specimens have been analyzed. These models had some differences such as bolt arrangement and the presence or a...

Prefabricated beam–column connections are the most vulnerable components of prefabricated buildings during earthquake events. The seismic performance connection is functional as critical component plays a key role in structural safety. This study aimed to develop novel hybrid concrete (HPC) connection, combining with wet and dry techniques, enhance frames. A quasi-static experimental investigat...

In this paper mathematical formulation for buckling analysis of a column and vibrationanalysis of a beam is presented. The beam and the column is assumed to be non-uniform and cracked.Using calculus of variations, the problem is expressed as an optimization problem. A technique ofoptimization is used for analysis of buckling load. Considering the similarity between the governingequation for buc...

Many RC frames built without seismic provisions between the ’50’s and ’70’s need structural upgrade in order to match the minimum requirements of new building codes. Generally, the critical region of the strengthening design is represented by the beam-column connection. The strength hierarchy governs the upgrade requiring to protect the column and the panel so that the formation of a plastic hi...

This paper presents the development of a composite cold-formed steel (CFS)-rubberised concrete (RuC) semi-rigid moment-resisting connection suitable for framed building structures. The comprises built-up tubular beam and column sections connected using side-plate screwed fasteners infilled with rubberised concrete. A detailed finite element analysis validated against physical tests is employed ...
