Introduction
The 25 # angle steel (Q460 material) is one of the most extensive applied cross-section material domestic and overseas.
To save the calculation time, take a section roller with pass, definite the material as rigid body, and the related parameters: density 785000, expanding 100 times, saving time; the Poisson's ratio 0.3, the elastic modulus 2.1e11; restrict all translations and X and Y rotation.
Choose the Rolling material model multi-linear kinematic strengthen model[6], and the related parameters: density 785000; elastic modulus 0.363; by calculation choose the deformation resistance selection σK1 = 240Mpa, σK2 = 209 Mpa, σK3 = 188 Mpa; the tangent modulus 2e10.

Spalling in concrete is a complex phenomenon and is primarily dependant on material (e.g. strength, water/cement ratio, fibres content) and environmental (e.g. heating rate, load level, curing humidity).
Many material and environmental factors have been identified from experiments[3-5] as influencing spalling of concrete in fire.
