本文在PK预应力混凝土双向叠合板、预应力方向叠合板的静力试验研究的基础上,对PK预应力混凝土非预应力方向拼接叠合板受力性能进行研究,主要研究内容如下:通过对PK预应力混凝土拼接叠合板的静载试验,研究了非预应力方向拼接叠合板的受力机理:变形性能、受弯承载性能、裂缝开展规律、钢筋、混凝土应力分布等特点; Based on the static test research of PK prestressed concrete composite slab and prestressed composite slab, the mechanical properties of PK prestressed concrete non-prestressed composite slab are studied. The main research contents are as follows: The static load test of prestressed concrete spliced ​​plywood was carried out to study the mechanical characteristics of spliced ​​plywood under non - prestressed direction: deformation performance, flexural bearing capacity, crack initiation law, stress distribution of reinforced concrete and concrete.
