The construction industry in Australia is introducing efficient and economical long-span trapezoidal profiled steel sheeting for composite flooring systems. Australia is a world leader in the research of composite structures. Composite beams undergo deformations because the concrete creeps and shrinks, and because the slab slips relative to the steel joist. Surprisingly little research has addressed these issues collectively; they are of paramount significance with trapezoidal decks and research is much-needed. This research will investigate the interaction of creep, shrinkage and partial interaction in these composite beams, producing valuable design guidance to keep Australian research and practice at the forefront internationally.

澳大利亚的建筑业正在采用高效、经济的大跨度梯形压型钢板用于复合地板系统。澳大利亚在复合材料结构研究方面处于世界领先地位。由于混凝土的蠕变和收缩，以及板相对于钢托梁的滑动，组合梁会发生变形。令人惊讶的是，很少有研究集体解决这些问题;他们是至关重要的梯形甲板和研究是非常必要的。这项研究将调查这些组合梁中的徐变、收缩和部分相互作用的相互作用，产生有价值的设计指导，使澳大利亚的研究和实践处于国际前沿。
