Abstract

The connection with opening on beam web is analyzed by Finite Element Program ABAQOUS. The optimal opening sizes and location are determined under the static loads. The factors to influence the formation of plastic hinge in beams and columns withstand static load are considered. Conclusions are drawn that the formation position is not only related with the web height h, but also with flange width b. The result provides us with a theoretical basis for specific engineering practice.

Keywords: Steel frame, web opening, plastic hinge, connections.
