Study on the Effect of Blocks on Seismic Performance of Improved Multi-Ribbed Slab Structure

Abstract:

In order to confirm the calculation model of multi-ribbed slab structure and transmission of earthquake action, this paper improved existing multi-ribbed slab structure. The calculation model of improved multi-ribbed slab structure confirmed the stress relationship among three seismic fortification lines, and the transmission of earthquake action became clear, the same calculation model could be applied in structural analysis. For studying the features of characteristic parameters of restoring force changing in the first seismic fortification line, blocks, and correcting the parameters, the experimental study was carried out. The experiment shows that when a unidirectional horizontal load was applied, that blocks in grid frame could be regarded as a slanted strut that with specific section and elasticity, the ideal slanted struts nominal elastic modulus is roughly in 20~60 N/mm2.
