Abstract

Abstract

Tubular hollow slab is the hollow slab whose internal mold is permanent internal mold of GBF serial highstrength thin-wall pipe. Experimental study on the behavior of plastic internal force redistribution of two kinds of tubular hollow slabs which have different arrangement manner of the high-strength thin-wall pipes was conducted.One of the experimental slabs was called parallel slab inside which the GBF high-strength thin-walled tubes wereplaced to be parallel with the span direction, the other was called vertical slab inside which the GBF thin-walledtubes were placed to be vertical with the span direction. It was indicated from the study that the tubular hollowcontinuous slab had good performance of plastic internal force redistribution. The parallel slab could meetrequirements of the bearing capacity and the regular service when the value of moment modulating is 30. 7 % at least.And the vertical slab could meet requirements of the bearing capacity and the regular service when the value ofmoment modulating is 27 % at least. And, the moment-curvature relationship of section approximately conforms tothe constitutive model of two straight lines.
