Practical design method, precise calculation design method, common simplified design method and equal strength connection design method.
1. The practical design method is to splicing and connecting according to the net cross-sectional area of ??the connected flange, and the connection of the web is calculated according to the shear force acting on the splicing position, and the net cross-sectional area of ??the web should be The shear force of 1/2 of the shear capacity or the sum of the bending moments of the members is determined by dividing the shear force obtained by the net span length of the member.
Second, the exact calculation design method is that the flanges and webs of the connected members share the bending moment at the section according to the ratio of their moment of inertia, and the shearing force is all borne by the web.
Third, the commonly used simplified design method is to bear all the bending moments according to the flange of the member, and the web bears all the shearing force to carry out the splicing design.
Fourth, the equal strength design method is to splicing according to the strength of the connected flange or the net cross-sectional area of ??the web. The principle of anti-seismic node design follows the principle of stress reduction and stress-saving and easy processing and installation. The most important point is to satisfy the principle of strong connection of weak components and avoid the overall damage of the structure due to weak connection. The purpose of the equal-strength joint design method is to make the bearing capacity of the joint of the member equal or higher than the bearing capacity of the member. Therefore, the equal-strength joint design method is often used for the structural splicing design of the structure according to the seismic design or the elastoplastic design to ensure the continuity of the component and good ductility.
