Abstract

This paper presents experimental and numerical studies to investigate the mechanical behaviour of bolted lap joints at elevated temperatures. The load-deformation curves, failure modes, and resistance values of the specimens were obtained from experimental studies. A solid finite element model generated using ABAQUS software was validated and verified by the experimental results and analytical models to investigate the different failure modes and predict the fire resistance of bolted lap joints at elevated temperatures, respectively. Then, the component-based finite element model (CBFEM) was prepared to analyse the fire behaviour of bolted lap joints as an alternative to design specifications for structural fire engineers. The CBFEM was verified by the validated solid model and analytical models in terms of load-deformation curve, fire resistance, and failure modes. Parametric studies were performed to investigate the influence of several parameters on the fire response of bolted lap joints. The study shows that the CBFEM may be used to design bolted lap joints at elevated temperatures and the 5 % limit strain for plates proposed in EN 1993-1-5 can be applicable for predicting the fire resistance of steel connections.

高温条件下螺栓搭接接头的数值设计计算
本文通过实验和数值研究来探讨螺栓搭接接头在高温下的机械性能。实验研究获得了试样的载荷-变形曲线、失效模式和阻力值。利用 ABAQUS 软件生成的实体有限元模型通过实验结果和分析模型进行了验证,分别研究了螺栓搭接接头在高温下的不同失效模式并预测了其耐火性。然后,编制了基于构件的有限元模型(CBFEM)来分析螺栓搭接接头的防火行为,作为结构防火工程师设计规范的替代方案。CBFEM 在载荷-变形曲线、耐火性和失效模式方面得到了经过验证的实体模型和分析模型的验证。还进行了参数研究,以探讨多个参数对螺栓搭接接头火灾响应的影响。研究表明,CBFEM 可用于设计高温下的螺栓搭接接头,EN 1993-1-5 中提出的板材 5 % 极限应变可用于预测钢连接的耐火性。

期刊介绍: Fire Safety Journal is the leading publication dealing with all aspects of fire safety engineering. Its scope is purposefully wide, as it is deemed important to encourage papers from all sources within this multidisciplinary subject, thus providing a forum for its further development as a distinct engineering discipline. This is an essential step towards gaining a status equal to that enjoyed by the other engineering disciplines.
