With the improvement of the level of architectural science and technology and the modern development of the residential industry, higher requirement on building materials and environmental protection was brought forward.
Various new materials and new structures emerged as the times require.
At this point, numerical results are larger than experimental data, this maybe related to the treatment of stiffness matrix after material crazing in ANSYS, but on the whole, the two curve are fit well.
