针对新型钢交错桁架结构,提出了一种简化的抗火分析方法,采用APDL语言对ANSYS进行了二次开发,编写了相关宏文件。采用VB开发前台中文界面,将ANSYS作为子程序调用,实现了钢交错桁架结构抗火分析软件FRASST1.0的开发,使用户能够通过在友好的中文界面内仅输入相关的基本参数即可完成该体系的抗火分析,大大提高了分析效率,将对促进该体系抗火的研究和推广应用起到积极的作用。
Aiming at the new staggered truss structure of steel, a simplified method of fire resistance analysis was proposed. The APDL language was used to develop ANSYS for the second time and related macro files were prepared. Using VB to develop the Chinese interface in the foreground and ANSYS as a subroutine call, the FRASST1.0 software for fire resistance analysis of staggered truss structure was developed, enabling the user to complete the FRASST1.0 by inputting relevant basic parameters in a friendly Chinese interface The analysis of system fire resistance has greatly enhanced the efficiency of analysis and will play an active role in promoting the research and popularization and application of this system against fire.
