Experimental Study on Seismic Behavior of Foam Concrete Composite Wall

Abstract

The construction industry consumes a lot of resources and energy. In order to achieve the goal of social sustainable development, the concept of building energy conservation has been paid attention to once it is proposed. The development and utilization of new energy-saving wallboard has become one of the main directions of building energy-saving development.A new type of fabricated composite wall with good seismic performance, economy, energy saving and environmental protection is designed and manufactured in this experiment. The composite wall is made of lightweight foam concrete as the main body, and inclined grid reinforcement cage is arranged inside. By means of pseudo static test, the failure process and failure characteristics of foam concrete composite wall specimens are studied, and the bearing capacity, hysteretic behavior, stiffness and ductility of the specimens are analyzed, and the seismic index of the specimens was compared with that of the block wall of the same size. During the test, the foamed concrete composite wall specimens with inclined grid bars have good cooperative performance with the edge frame, reasonable failure form and good ductility. Compared with the block wall, the foam concrete composite wall specimen has better performance in ultimate bearing capacity and energy dissipation, and can provide technical support for its practical application, so that it can be applied to the building energy-saving industry and create certain economic and social value.
