Iran is countries that is at high risk of earthquakes. Therefore, the necessity of the resistance of all components against lateral loads is normal and connections are no exception. The bonding strength is very high in bearing resistance to lateral loads and ductility.
One of the problems is the volume connections of the reinforcement in the area of the connection area
Concrete bug fixes and causes inappropriate fitting. The high resistance rod with an elongation parameter can solve this problem
In this paper, using modeling with ABAQUS finite element software, the parameters of resistance, hardness, energy absorption, formability and cracking in connection with the cross section of columns with ordinary steel and high performance and increasing the geometric dimensions of the column have been compared and compared
The increase in the number of column amateurs with ordinary steel and high strength does not affect the performance of the beam to column connection. However, the use of high performance steel has increased the bonding capacity of the connection with ordinary steel. The geometric dimensions of the column have a significant effect on the connection performance, with the increase in the column dimensions, the parameters of "ultimate strength", "hardness" and "absorption energy absorption" increased and "ductility" had a decreasing trend
In order to optimize the use of high-strength steels in combination with concrete it is possible to achieve the same result and performance of bonding with ordinary steel, taking into account the lower volume of high-quality steels instead of conventional steel.
