Precast concrete structures in Iran are generally designed as continuous columns with hinged beams, thereby making them simple frames. In this system in site show walls in two directions of buildings guaranteed lateral resisting system. However, in order to obtain a seismic resisting frame, the connection between beam and column should be moment resisting and ductile, allowing the formation of ...

This paper aims to provide an experimental support on seismic performance evaluation of the steel braced truss-RC (reinforced concrete) column hybrid structure, which could be applied as the air-cooled supporting structural system in large-capacity thermal power plants located in strong earthquake prone regions. A series of pseudo-dynamic tests (PDTs) and quasi-static tests (QSTs) were performe...

In this research, the structural behavior of reinforced concrete brackets cast with containing different types fibers was studied. Seven samples corbels were and tested. One specimen without fiber as a reference, other made six at constant volume fraction (1% total volume). The used in research two materials: steel polyolefin. polyolefin fiber, five remaining samples, used. Straight, crimped, t...

To avoid the damage of connection due to overstrength beam strength, and alternation strength hierarchy in structural system, a novel precast concrete beam-to-column is proposed herein. In connection, replaceable energy-dissipation connector (REDC) was placed at bottom hidden corbel. addition, narrow vertical slot adjacent corbel reduce overstrength. First, features mechanical mechanism were di...

On the basis of test results nine steel-fiber high-strength concrete corbel specimens subjected to a vertical load, influence steel fiber content on shear performance corbels was analyzed. The softened strut-and-tie model (SSTM) used analyze strength corbels, taking into consideration contribution fibers. A calculation for is proposed, and database 26 created by using model. obtained according ...

This paper deals with the topology optimization of strut-and-tie models in non-flexural reinforced concrete members by using the Evolutionary Structural Optimization (ESO) method for plane stress continuum structures with displacement constraints. By means of systematically removing elements that have less contribution to the stiffness from the discritized concrete member, the actual load paths...

Abstract In this study a numerical simulation is developed using finite element (FE) software Abaqus, to assess and simulate the structural behavior of reinforced concrete column - short corbel assembly strengthened by bonding composite materials The objective presented reproduce considered structure as displacements, strain, mode damages, cracks propagation, ultimate force, main reinforcements...
