Study on Performance of Kiewitt Single-Layer Spherical Reticulated Shell Structure under the Action of Fire

Abstract:

Under the condition of high temperature, steel basic mechanical property index such as strength, elastic modulus falls sharply. Once there is a fire, long-span reticulated shell has serious damage. This paper, taking Kiewitt reticulated spherical shell as an example, uses ISO - 834 standard temperature - time curve to simulate fire and analyze the distribution of temperature field calculation and mechanical. Analysis by using transient thermal analysis in ANSYS software. Through ANSYS software to analog fire resistant properties of reticulated shell under the action of local fire resistant properties, it is concluded that the fire in the different parts of the structure on the structural deformation and destruction of the structure form, to a certain extent, reflects the overall structure fire resistance of spatial reticulated shell.
