Abstract

In order to study the seismic behavior of the composite wall of sludge ceramsite foamed concrete block, two specimens with reinforcing rib in U-shape block under cyclic loads are studied in the paper. Based on the experiment, the damage process, failure mechanism, hysteresis curves, initial stiffness, stiffness degradation and energy dissipation are discussed. Test results indicate that the composite wall of sludge ceramsite foamed concrete went through three stages: elastic stage, elastoplastic stage, failure stage, and the failure mechanism is reasonable; both of the two specimens have good ductility and energy dissipation capacity, and the increasing of reinforcing rib can effectively improve the seismic performance of wall. Whereas, in addition to the set of reinforcing rib itself, the mutual coupling action between blocks, reinforcing ribs and boundary elements may be a factor affects the seismic behavior of the CW. And, the practical application of the CW should be further compared and investigated.
