03.15: Experimental tests and model study on self‐drilling screws connections subjected to shear

Abstract

Research on shear resistance of the steel sheeting plates with thickness from 0,50 to 1,50 mm connected by self-drilling screws is undertaken and presented in this paper. One screw type with one diameter has been used. This kind of the single lap fastening is commonly used in a steel sheeting. Experimental and theoretical data about a connections slip and shear stiffness is a one of most important issue in case of a stressed skin diaphragm action problems. At the present practice the linear model of connections is effectively used however for more advanced analyses, the nonlinear models have to be taken into consideration. These are necessary in case of the advanced design and implementation of the stressed skin action in the steel structures covered by the corrugated metal sheeting. Such a model study is presented herein which intend to investigate the general connection behaviour where the main selected variable is the plate thickness. The test are performed according to the current standards EN 1990 and ECCS handbooks. It leads to a statistical evaluation of proposed functions for the design slip of fasteners and its limits. The theoretical basis of experimental tests under the shear load is presented.

Research on Initial Behavior of Screwed Lap Connections of Thin Plates – Experimental Tests and FEM Analysis

“…Thus, it is necessary to obtain the single-connector parameters and select a method to implement them in a suitable configuration. To confirm these requirements, experimental investigations of self-drilling screwed connections under shear of thin plates were performed [2] and now, they are verified by a FEM parametric model developed in the ANSYS software. Such models can also be treated as a proposition of alternative tool for manufacturers who want to check their products with reduced costs in relation to lab tests.…”
