Summary:
abstract是什么意思
∙ Composite floors are frequently ud in multi-storey building construction.
∙A composite slab compris steel decking, reinforcement and cast in situ concrete. When the concrete has hardened, it behaves as a composite steel-concrete structural element.

∙Design of composite slabs requires consideration of the performance of the steel sheeting as shuttering during construction and as reinforcement to the hardened concrete slab.西安事变的历史意义
