چکیده
Abstract Recent devastating earthquakes worldwide pointed out the importance of seismic detailing and their influence on observed damage subsequent repairability reinforced concrete buildings. Several studies post-earthquake observations remarked role beam–column joints (BCJs) global building response effectiveness transverse reinforcement in increasing joint shear strength ultimate deformation. Although number experimental theoretical focused BCJs, mechanical behaviour is still a discussed topic. This resulted design approaches available code or standards that lead to different quantity stirrups. study focuses BCJs 10-story prototype designed according Japanese tested 2015 E-Defense shaking table. First assessment at (building) local (joint) level performed intensities considering base slip fixed configurations. A refined numerical model then developed validated against results. Then, stirrups are re-designed international (ACI, EC8, NZS) models developed. The results compared terms interstorey drift demand strain. Finally, comparison expected varying approach proposed.

Performance based seismic assessment of bridges designed according to Canadian Highway Bridge Design Code
Recent research efforts have focused on the development of performance based seismic design methodologies for structures. However, the seismic design rules prescribed in the current Canadian Highway Bridge Design Code (CHBDC) is based largely on force based design principles. Although a set of performance requirements (performance objectives) for different return period earthquake events have b...
متن کاملA Multi-layer Architecture Based on MCDM Methods to Select the Best E-Readiness Assessment Model According to SWOT Analysis
E-readiness is one of the major prerequisites for effective implementation of e-government. For the correct implementation of e-government, it is needed to accurately assess the state of e-readiness in desired community. In this regard, there are models to assess, but the correct choice of model is one of the most important challenges in this area. The process of evaluating and selecting the ap...
متن کاملA Comparison of Seismic Safety of Steel MRF Designed According to Different Editions of Iranian Seismic Code
In this paper, efforts are made to compare the safety of steel moment resistant frames designed according to different editions of the Iranian code of Practice for seismic resistant design of buildings. Also, failure risk of a low and medium height frame which designed for high and low seismicity regions according to three editions of the code are evaluated. First, the testing cases were design...
متن کاملSeismic fragility assessment of RC moment resisting frame buildings designed for different editions of Iranian seismic design code
Background and objective: Developing fragility and vulnerability functions are important tools in seismic reliability assessment of buildings and are widely used in regional seismic risk studies. To date sufficient studies for developing analytical fragility functions for Iranian code-conforming buildings have not been carried out. Performing such studies are necessary to assess the adequacy of...
