1, a useful gauge Design
Useful planning method is based on the convergence of the flange is the net cross-sectional area of ​​strength and other conditions splicing convergence, while convergence in addition to the role of the web is calculated shear splice in position, but still should be the net cross-sectional area of ​​the shear web Capacity 1/2 length or net cross member ends the moment divided by the member to determine the resultant shear. 2, accurate calculation Design
Accurately calculate the Planning Act is the convergence of the web and flange member in charge of the proportion of their cross-sectional moment of inertia at the moment, but all borne by the shear webs.

3, commonly used to simplify the design method
Common streamline the planning process is to bear all the moments by member flange and the web to assume all of the shear splice planning.

4, etc. Strength Design
Planning Act and other strength is the net cross-sectional area is conditional convergence flanges or webs of equal strength to be spliced. Seismic node planning to follow the principle of force except clear cut stress concentration and to facilitate the installation process, the most important thing that is to meet the strong convergence of weak member of principle, leaving the structure to prevent weak convergence of all the destruction. Cohesion strength purposes is to make the planning process that is carrying capacity and component capacity member Cohesion flat or higher than the component capacity. So the strength of the convergence plan and other methods often used by construction or planning elastoplastic seismic planned splicing member planning to ensure continuity and outstanding ductility member.
