Study on Pseudostatic Test of Frame-Supported Multi-Ribbed Slab Structure

Abstract eng:
This paper presents the results and discussions of experimental study on FSMRSS specimen. The specimen is four scaled models (three 1/2 scale two-storey two-bay models and one 1/3 scale three-storey two-bay model) of FSMRSS. The pseudo-static experiments of the specimens have been executed. The seismic performances under low cyclic loadings, such as the failure procedure, failure mode, bearing capacity, deformation features, stiffness, hysteresis characteristic and anti-collapse performance, are studied. The experimental results show that the failure procedure of FSMRSS specimen take place in the order of infilled silicate bricks, reinforced concrete rib beams, reinforced concrete rib columns, outer frame and supporting frame; the deformation and failure mainly concentrate on second storey (multi-ribbed slab structure storey), the specimen shows good load carrying capacity even in large deformation condition and high restoring characteristics. The conclusion obtained provide reliable basis for the application of FSMRSS to the buildings with large space at the bottom.
