The joints of steel structural parts are very important.Appropriate connection methods should be adopted to make the joint design consistent with the simplified structural calculation model.Most of the structural damage in the past occurred at the nodes,so the nodes must be carefully designed and constructed.Advanced and reliable connection methods are used. Steel structural parts will be subjected to various forms of action (load,uneven foundation settlement,temperature,etc.) during use. so the steel should have good mechanical properties (strength,plasticity,toughness) and processing properties (cold and hot working and Welding performance) to ensure the safety and reliability of the structure.There are many types of steel,but only a few meet the requirements of steel structural parts,such as Q235 in carbon steel,16Mn in low alloy steel,and 20 manganese vanadium steel (20MnV)for high-strength bolts.
