Structural Safety and Seismic Evaluation of Steel Structure Design in Construction Engineering

Abstract

In this paper, according to the current national reliability evaluation standard of civil buildings, the safety detection and evaluation and seismic bearing capacity checking calculation of a pure steel frame structure building are carried out. Through calculation, the safety rating and seismic capacity level of the building are obtained. The results provide a certain reference for the detection, identification and seismic checking calculation of similar pure steel frame buildings. This paper also expounds the purpose and main contents of seismic performance evaluation of steel structures, and summarizes the failure characteristics of steel structures under earthquake. In this paper, it is proposed that the subsequent service life and seismic fortification category of existing steel structures should be determined in the seismic appraisal. This civilization determines the basic fortification intensity and seismic acceleration in this area, as well as the structural system and component layout. Finally, this paper constructs the identification technology related to the checking calculation of connection and seismic bearing capacity..
