- Abstract:
-
Through the test of a new composite structure model for multi-storey housing under vertical loading, the stress, cracks, deformation and failure patterns of beams, columns and supports during the normal service stage and bearing capacity limit state of composite structure were studied. The results show that when the beam and column cross-section is 250 mm×250 mm, the support cross-section is 120 mm×120 mm, and the bearing area is 4.2 m× 4.2 m, the cracks and deflections of the beams and columns are much smaller than the concrete specification limits when the load reaches the standard value and design value of the general residential vertical load. The failure form of the composite structure under vertical load is the beam hinge mechanism system. And it is recommended that the height of the beam should be 1/14~1/10 of the actual span.
