Steel component design There are several ways to connect?
Practical design method, design accurate calculation method, commonly used to simplify the design method and design methods, such as the strength of the connection.
A practical design method is based on the flange is connected net cross-sectional area of equal strength conditions splicing connection, and web connections are calculated in addition to the role of shear splice location, but still should be the net cross-sectional area of the web net shear capacity of 1/2 or members at both ends of the bending moment divided by the length of the resulting cross member shear to determine.
Second, the accurate calculation method is designed to be connected to the flange and web member proportional share their moment of inertia of section at the moment, and shear borne entirely by the web.
Third, the common law is to simplify the design bears all the moments by member flange and the web to assume all of the shear splice design.
Four, and so on the strength design method is based on the condition of net cross-sectional area of the flange is connected or webs of equal strength for stitching. Seismic design follows the principles of the nodes in addition to the force clearly reduce stress concentration and ease of processing installation outside, the most important thing is to satisfy the principle of connecting weak and strong member, to avoid leaving the structure connecting the weaker overall damage. Purposes strength design method is to make the connection with the carrying capacity of the bearing capacity of member connecting member is equal to or greater than the component capacity. So often, such as the strength of the connection design methods for structural seismic design or by elastic-plastic component design stitching designed to ensure continuity member and have good ductility.
