A substantial amount of research has been conducted over the past 10 years on the development of composite timber floor systems consisting of a concrete slab and timber beams that are connected using shear connectors. A slightly different version of this type of composite systems is to use a cross laminated timber (CLT) or structural composite lumber (SCL) deck inserted between the beams and concrete slab. This modified concept originated from the profiled steel-concrete slab composite system which is widely used in long-span floor construction. The wood deck serves as formwork for the concrete slab and reduces the thickness of the concrete slab. The economics of such a 2-layer deck system is prohibitive due to the relatively high cost of CLT and SCL.

在过去的10年中，已经进行了大量研究，以开发由使用剪切连接器连接的混凝土板和木梁组成的复合木地板系统的开发。这种类型的复合系统的一个略有不同的版本是使用横梁和混凝土板之间插入的交叉层压木材（CLT）或结构复合木材（SCL）甲板。这个修改后的概念源自介绍的钢结构板复合系统，该系统广泛用于长跨底层构造中。木甲板是混凝土板的模板，并减少了混凝土板的厚度。由于CLT和SCL的成本相对较高，因此这种2层甲板系统的经济性非常高。
