Study on the Effect of Grid Beam 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 the 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, this calculation model could be applied in structural analysis. For studying the effect of characteristic parameters of restoring force changing in the second seismic fortification line on seismic performance, and correcting the parameters of grid beam, this paper analyzed push-over model of the second seismic fortification line to get the static pushover curve. According to the study, the amount of steel bar in grid beam and sectional dimension of grid beam made the major effect on characteristic parameters of restoring force in the second seismic fortification line, concrete grade of grid beam is a unconsidered factor. Nominal elastic modulus of filling materials didnt much affect the yield strength and yield displacement of the second seismic fortification line, but made significant effect on post-yield strength.
