Impact performance of reinforced concrete frame, especially on the nonlinear behavior of connections in the Persian month Tir Lrz·hyy middle column

The aim of this study connect the Persian month Tir Analysis - Column Frames reinforced concrete flexural performance levels, especially in the finite element method is different. In this article by making numerical models serve as examples and S·hlalvsvl Kmhzynh in finite element software package ANSYS, analyzes Persian month Tir on the middle joints - the column of concrete structures according to the bylaws of Iran "ABA", IX topics National Building Regulations and Standards in 2800 are designed to do and bending behavior of these joints in concrete frames, particularly in levels of performance have been investigated. In this study the behavior of more than 30 middle connecting the Persian month Tir - Column nonlinear numerical methods to help evaluate and place in plastic hinge set up the first connection and the overall performance of the frame is on the behavior of the connection. Moreover, due to finite element models of specific features, works of other variables such as amount Khamvtha connection, the compressive strength of concrete, steel Jaryshdgy resistance, the amount of longitudinal bars Tir, a central force on the column connection behavior is evaluated.
