Stress-strain state 4-way end-plate beams to column connection

Abstract

With the development of construction technology of multistory buildings with a steel frame, the use of 4-way rigid joints for beams to column connection becomes especially relevant, as it allows to eliminate the need for arrangement of braced in the frame of a building. Residential building requires compact size of construction joint assemblies and no additional issues during finishing and decorating works. The article describes lightweight end plate joints of 4-way beams to column connection as one of the most compact, economical and easy to assembly type of connection. The article analyzes numerical models of such assemblies created in the ANSYS Mechanical software package. The variants of assemblies with 20- and 30-mm thick end plates are considered, the stress state of the column wall in 2-way and 4-way connection is compared, and the influence of end plate thickness on the stress state of bolts in such assemblies is evaluated. The result of the analysis brings us to the conclusion that experimental research is needed to create an analytical procedure for calculating of such joints.
