摘要

本文介绍了一种可用于预测后张箱梁防火性能的简化计算方法。尽管是一种可燃材料,但木梁在火灾中表现良好。然而,如果要避免不希望的剪切破坏模式,则需要仔细设计后张箱梁。提出了一种简化的计算方法,可用于设计这些梁,同时使设计者能够预测梁何时以及如何可能失效。以两种梁的几何形状为例,验证了该计算方法预测可能的失效模式和失效时间的能力。最后,讨论了可能对该方法进行的改进以及为验证该模型而进行的实验测试。

Simplified Calculation for Fire Performance of Post-Tensioned Timber Box Beams
This paper describes a simplified calculation method that can be used to predict the fire performance of post-tensioned timber box beams. Despite being a combustible material, timber beams can perform well in fire. However, post-tensioned timber box beams need to be carefully designed if an undesirable shear failure mode is to be avoided. A simplified calculation is proposed which can be used to design these beams while giving the designer the ability to predict when and how the beam is likely to fail. Two beam geometries have been used as examples to demonstrate the ability of this calculation method to predict the likely mode and time of failure. Finally, potential improvements that may be made to the method as well as experimental tests that will be conducted to verify the model are discussed.
