浅谈用EVACNET4软件建立建筑网络模型

Preliminary discussion on establishing the model of building network by EVACNET4

EVACNET4是一个被广泛使用的人员疏散网络模拟软件 ,由美国佛罗里达大学开发。该软件将建筑物结构以网络的形式描述 ,模拟人员在这一网络内的流动 ,直至所有人员最终到达规定的安全地点为止。应用该软件进行人员疏散模拟的关键是建立建筑的网络模型 ,该模型应能如实地反映建筑物的内部结构布局。从节点划分、路径设置两个方面详细描述了建筑网络模型的建立以及某些特殊情况处理的一些技巧 。

EVACNET4 is a network-typed occupant evacuation software which is developed by university of florida and is widely used in fire safety engineering. The building layout is described in form of a network in which occupant move until they reach the predefined safe places. The key to simulate occupant evacuation successfully by using this software is to build the building's network model which can represents the building's interior layout reasonably. This paper presents the rules to define nodes and arcs when setting up building's network model and summarize some techniques which can deal with some special problems.
