Abstract


\. Steel structure , on the other hand , has a large building within the structure of the proportion of irreplaceable in the field of steel structure , in-depth and summary of great practical significance for the exploration of the subject . This article aims to load the dynamic response of steel beam-column joints in shock as the direction and content through the use of finite element software ABAQUS simulation analysis . In the analysis, the first response of steel structures under impact loading power simulation . Higher strain rate during the impact of steel components , the choice of material constitutive , taking into account the strain rate effect on the strength of the material ; assumed that the beam-column connections does not occur destroyed during the analysis by analyzing the response of the structure , to establish the feasibility of the model and calculation , explain the justification . Secondly, considering the impact of the beam parts , these three factors , the initial speed of the collision object and its elastic modulus 18 of the finite element model to explore in the determination of impact load under the influence of various factors , and calculated on the basis of the results detailed discussed the impact of the above factors on the beam , including the end of the girder cross-section stress distribution and the deflection of the beam distribution pattern . Finally, the ordinary , dog bone and web openings are three types of nodes simulation comparative study . The article gives three types of nodes to the ends of stress during the impact , the focus of the end of the girder and weaken at maximum stress , strain and deflection of the beam . Found in these three types of nodes in the dog bone node delay destroy the ability of the end portion preferably while the webs hole is not obvious from the comparison data .
