The elasto-plastic model of the steel material was implemented for the dynamic analyses.
In the numerical calculations the parameters of the non-linear elasto-plastic steel material were taken from the experiment.
Figs3a and 3b show both, the experimental and numerical, tensile test of the steel material.

Since these materials could tend to become conventional building materials in the near future, some normative tests must be developed in order to allow them to meet current standards of the building industry.

The battle of the plane roof and sloping roof in domestic is very intense [4-14], the main points are as follow: (1) Sloping roof is construct waterproofing while flat roof is material waterproofing.
Roof slope Roof slope [17,18] should be determined by the roof structure, roof grass-roots category, waterproof construction form, material properties and local climatic conditions, GB 50352-2005 set the drainage gradient as 2% to 50%.
The structure of sloping roof Materials used in the sloping roof structure is divided into: reinforced concrete structures and light steel structures.
