摘要

本文研究了一种适用于轻型结构的新型矩形钢空心截面连接方式。这些接头是通过将其中一个成员部分插入另一个成员，然后使用自钻螺钉有效地连接它们来制造的。两种型材的宽度必须匹配10毫米的差异，这允许使用4毫米厚的型材为外层。自钻螺钉放置在两个侧面，并接受剪切。关节易于安装，降低了执行成本。如果充分确定由自钻螺杆及其周围区域组成的单个部件的线性刚度，则可以通过一些简化的假设来解析计算关节的旋转刚度。本文采用简化的基于构件的方法，给出了一些实验结果和半刚性节点设计的分析建议。结果表明，这些接头和建议的配方适用于轻钢结构，这些结构可以很容易地用普通工具制造和安装，而不需要专门的专业知识。

Characterization of semi-rigid RHS T-joints with self-drilling screws

This paper presents a study on an innovative type of joint between rectangular steel hollow sections (RHS), which can be used in light structures. These joints are fabricated by partially inserting one of the members into the other and then using self-drilling screws to join them effectively. The width of both profiles has to match with a difference of 10 mm, which allows the use of 4 mm thick profiles for the outer piece. The self-drilling screws are placed on both lateral faces, and they are submitted to shear. The joints are easy to mount, reducing execution costs. The rotational stiffness of the joint can be analytically calculated through some simplified assumptions if the linear stiffness of the individual component, composed of the self-drilling screw and its surrounding area, is determined adequately. This work presents some experimental results and the analytical proposal for their design as semi-rigid joints, by applying a simplified component-based method. The results demonstrate the applicability of these joints and the proposed formulation to light steel structures that can be easily fabricated and mounted with ordinary tools and without specific expertise in execution.

期刊介绍： Thin-walled structures comprises an important and growing proportion of engineering construction with areas of application becoming increasingly diverse, ranging from aircraft, bridges, ships and oil rigs to storage vessels, industrial buildings and warehouses. Many factors, including cost and weight economy, new materials and processes and the growth of powerful methods of analysis have contributed to this growth, and led to the need for a journal which concentrates specifically on structures in which problems arise due to the thinness of the walls. This field includes cold– formed sections, plate and shell structures, reinforced plastics structures and aluminium structures, and is of importance in many branches of engineering. The primary criterion for consideration of papers in Thin–Walled Structures is that they must be concerned with thin–walled structures or the basic problems inherent in thin–walled structures. Provided this criterion is satisfied no restriction is placed on the type of construction, material or field of application. Papers on theory, experiment, design, etc., are published and it is expected that many papers will contain aspects of all three.
