本文介绍了一个多层多开间建筑中双向钢筋混凝土板的火灾行为的数值模拟。这座建筑是正方形的，每个方向有三个开间。混凝土板由周边框架、四个内部柱和无内部梁支撑。假设同一层混凝土板的所有九个开间都受到来自下方的火灾。使用了两把火;标准ISO 834火灾持续4小时，基于ISO 834火灾的参数火灾持续1小时，温度在另外2小时内衰减到环境温度。火灾的影响进行了描述的弯矩的重新分配和发展的张力场行动在板。
This paper describes numerical modelling of the fire behaviour of two-way reinforced concrete slabs in a multi-storey multi-bay building. The building is square, with three bays in each direction. The concrete slab is supported by a perimeter frame, four internal columns and no internal beams. It is assumed that all nine bays of the concrete slab at one level are subjected to fire from below. Two fires were used; the standard ISO834 fire for a four hour duration, and a parametric fire based on the ISO834 fire for one hour with the temperatures decaying to ambient in another two hours. The effects of the fires are described in relation to the redistribution of bending moments and the development of tension field action in the slab.
