This paper describes a component-based model for simulating the behaviour of flexible end-plate connections between beams and columns in steel framed structures in fire conditions. In this method, a simple steel connection was split into a number of active components for which mechanical properties are represented by non-linear springs. The behaviour of a steel connection is then determined by assembling the individual behaviour for each active component into a spring model. The component model presented in this paper is capable of predicting the behaviour of steel connections under varied loading conditions. It is also capable of predicting the tying resistance and critical components of failure for steel connections in fire. Compared with experimental test data, a good correlation with the simplified model has been achieved and this method, combined with finite element modelling, may be used to examine the performance of simple steel connections in fire conditions.

火灾中柔性端板连接的组件建模

本文介绍了一种基于组件的模型，用于模拟火灾条件下钢框架结构中梁与柱之间的柔性端板连接行为。在这种方法中，将简单的钢连接分为许多有效部件，这些部件的机械性能由非线性弹簧表示。然后，通过将每个活动组件的单独行为组装到弹簧模型中，确定钢连接的行为。本文介绍的组件模型能够预测在变化的载荷条件下钢连接的行为。它也能够预测火灾中钢连接的绑扎阻力和关键失效组件。与实验测试数据相比，已与简化模型建立了良好的相关性，该方法
