SEISMIC PERFORMANCE OF REINFORCED CONCRETE INTERIOR BEAM-COLUMN JOINT UNDER LOW RATIO OF COLUMN TO BEAM MOMENT CAPACITY

Seismic Behavior of Beam Column Joints in Reinforced Concrete Moment Resisting Frames

EVALUATION THE EFFECT OF STRONG COLUMN-WEAK BEAM RATIO ON SEISMIC PERFORMANCE OF OPTIMALLY DESIGNED STEEL MOMENT FRAMES

The present work is aimed at assessing the impact of strong column-weak beam (SCWB) criterion on seismic performance of optimally designed steel moment frames. To this end, different SCWB ratios are considered for steel special moment resisting frame (SMRF) structures and performance-based design optimization process is implemented with the aid of an efficient metaheuristic. The seismic collaps...

non-linear seismic behavior of concrete beam - column connections

a parametrik investigation was conducted to study the non-linear behavior of precast and cast-in-place reinforced concrete beam-column connections subjected to tabas seismic forces (1979). the behavior of these types of connections in a four stories structure with respect to strength, ductility , stiffness, and bond deterioration at the joint core are presented and discussed. calculation result...

Performance of the Modified Precast Beam to Column Connection Placed on a Concrete Corbel

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 ...

Finite Element Modeling of GFRP-Reinforced Concrete Interior Slab-Column Connections Subjected to Moment Transfer

A finite element model (FEM) was constructed using specialized three-dimensional (3D) software to investigate the punching shear behavior of interior slab-column connections subjected to a moment-to-shear ratio of 0.15 m. The FEM was then verified against the experimental results of full-scale interior slab-column connections reinforced with glass fiber reinforcement polymer (GFRP) bars previou...
