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年里，已经进行了大量的研究，对复合木地板系统的发展，包括混凝土板和木梁连接使用剪力连接件。这种复合系统的一个稍微不同的版本是使用交叉层压木材（CLT）或结构复合木材（SCL）甲板插入梁和混凝土板之间。这种改进的概念起源于压型钢板-混凝土板组合体系，这是广泛应用于大跨度楼盖结构。木甲板用作混凝土板的模板，并减少混凝土板的厚度。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令人望而却步。
