Abstract :

In the event of an earthquake environmental hazard, reinforced concrete buildings in Tehran, in addition to destroying and inflicting extensive human and financial losses, will lead to the production of construction debris and mass debris. In this study, the reliability analysis in 110 concrete buildings running in area one of Tehran with the assumption of variable compressive strength of concrete and yield strength of rebar has been investigated. That is, it has compared the flexural frame and the flexural frame with the shear wall. And this is slightly higher in shear walls. Also, in all tested rebar’s (environmentally friendly), the average yield strength was higher than the nominal strength. Regarding seismic performance, shear wall structure has less general and relative displacement than flexural frame structure. The results of reliability analysis showed that the use of shear wall system instead of bending frame can reduce damage to non-structural components and consequently reduce the production of construction debris and preserve the environment.
