Abstract: Compared with other structures, steel structures have many advantages, such as high strength, small weight, large ductility, good seismic performance, fast construction progress, flexible layout and reusable construction. However, the problem of fire resistance is its fatal flaw. Because the material properties of steel changed significantly with the temperature rising, especially the steel structure with cracks, which brought considerable losses to people's lives and property. Therefore, considering the material properties changed with temperature, we introduced the temperature load into the peridynamic constitutive equation to simulate the cracks propagation paths in steel structures with temperature rising.
