Some current building carrier plates adopt the connection structure that plastics or timber were made to connect building carrier plate and steel bar truss, and the connection structure that plastics or timber were made can exert an influence to the structure of building carrier plate.
We compare the elastic modulus of concrete with wood and plastic, respectively, as follows:
concrete elastic modulus: taking the common C30 concrete as an example, the elastic modulus of the concrete is 30000 MPa;
elastic modulus of wood: taking common larch as an example, the elastic modulus of wood is 10000MPa, which is about 1/3 of the elastic modulus of concrete;
elastic modulus of plastic: the elastic modulus of plastics is much lower, typically not more than 2000MPa, about 1/15 which is the elastic modulus of concrete.
The formula for calculating the deflection of the simply supported beam under the action of uniformly distributed load is as follows:
wherein q is the uniform load concentration, l is the span, E is the elastic modulus, I is the bending moment of inertia, EI is the bending stiffness of the beam, and b and h are the width and height of the beam respectively.
Therefore, if wood is used instead of concrete, the deformation of wood is about three times that of concrete under the same floor load, which is very disadvantageous for the structural design; on the contrary, if the wood and the concrete floor are made to have the same deflection, the thickness of the wood is about 1.44 times of the thickness of the concrete, which will affect the building clearance and is very disadvantageous to the building design.
If plastics are used to replace concrete, the deformation of plastics is about 15 times that of concrete under the same floor load, which is very disadvantageous for structural design; on the contrary, if the deflection of the wood and the concrete floor is the same, the thickness of the wood is about 2.47 times of the thickness of the concrete, which will also affect the building clearance, and is very unfavorable for the building design.
