Hysteretic Load Behavior of Pre-Casted Reinforced Concrete Shear Wall Systems With High Thermal Resistance Capability

Abstract

It is essential to determine the thermal conductivity and earthquake performances by developing earthquake-resistant building systems that have high thermal insulation properties that will be economical for people considering the need for energy deficit and low-cost earthquake-resistant residences in the world. This study aims to evaluate the seismic performance of pre-casted reinforced concrete shear wall systems with double layer high thermal resistance capability and compare to standard monolithic reinforced concrete shear wall systems with non-high thermal resistance capability. The coating material used for thermal insulation was developed as an inorganic, economical, easily applicable, high-fire resistance capable and not to cause the problems observed in the currently used products. In the research, new generation methods were used to reduce the unit weight of cement binder inorganic insulation material to low levels and provide high thermal resistance features. The seismic performance tests of the new double insulation layer, pre-casted reinforced concrete shear wall system were realized. The seismic performance of conventional reinforced concrete shear walls was compared with the developed system by testing lateral reversed cyclic loading that simulates the earthquake.
