Abstract

Corrugated web beams made of cold-formed steel components represent an economical solution for structures, offering high flexural capacity and deformation rigidity. For conventional corrugated web beams, made of thick plates for the flanges and thin sinusoidal steel sheets for the web, the elements can be joined by standard bolted end-plate connections. In the case of corrugated web beams made of thin-walled cold-formed steel components only, additional plates are required to accommodate the shape and position of the profiles. A large experimental program was carried out on corrugated web beams made of cold-formed steel elements. One of the objectives was to determine the capacity of these beams and the influence of several parameters on the response of the beam, but also very important were the end connections of these beams. The recordings obtained from the tests were used to validate a numerical model. Based on the validation of the numerical model, finite element analyses were performed to study four solutions for end connections to facilitate assembly, optimise the number of bolts, and increase the capacity and rigidity. Although the connection can be improved for assembling reasons with the presented solutions, the overall capacity is limited by the components subjected to compression that lose their stability.

冷弯型钢波纹腹板组合梁端部连接性能的数值研究

由冷弯型钢构件制成的波纹腹板梁代表了一种经济的结构解决方案，提供高抗弯能力和变形刚度。对于传统的波纹腹板梁，由厚板的法兰和薄正弦钢板的腹板制成，元件可以通过标准螺栓连接的端板连接。在仅由薄壁冷弯型钢构件制成的波纹腹板梁的情况下，需要额外的板来适应型材的形状和位置。对冷弯型钢构件波纹腹板梁进行了大型试验研究。其中一个目标是确定这些梁的容量和几个参数对梁的响应的影响，但也非常重要的是这些梁的末端连接。从测试中获得的记录用于验证数值模型。在数值模型验证的基础上，通过有限元分析，研究了四种末端连接方案，以方便装配，优化螺栓数量，提高承载力和刚度。虽然由于装配原因，连接可以通过所提出的解决方案得到改善，但总体容量受到压缩组件的限制，从而失去稳定性。Doi: 10.28991/CEJ-2023-09-04-01全文:PDF
