In reinforced concrete structures, the beam-column connection area has a considerable influence on behavior of structure. The use fiber-reinforced polymer FRP to strengthen connections in Reinforced structure can be one solutions transform this area, thus improving structure, which is achieved through carbon achieve high-strength Investigations have been conducted using finite element modeling....

The inelastic response of beam-column connections significantly affects the seismic performances of steel frames. Accurate models of beam-column connections are important both in understanding the seismic behavior and in design. An effective approach towards developing accurate models for connections is self-learning simulation, which is presented in this paper. The latter simulation method has...

the present study sets out to integrate the performance-based seismic design approach with the connection topology optimization method. performance-based connection topology optimization concept aims to simultaneously optimize the size of members and the type of connections with respect to the framework of performance-based seismic design. this new optimization concept is carried out for unbrac...

Punching shear capacity is a key factor for governing the collapsed form of slabs. This fragile failure that occurs at the slab-column connection is called punching shear failure and has been of concern for the engineers. The most common practice in evaluating the punching strength of the concrete slabs is to use the empirical expressions available in different building design codes. The estima...

Investigating the behavior of the box-shaped column panel zone has been one of the major concerns of scientists in the field.  In the American Institute of Steel Construction the shear capacity of I-shaped cross- sections with low column thickness is calculated. This paper determines the shear capacity of panel zone in steel columns with box-shaped cross-sections by using artificial neural netw...

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...
