Pset_MaterialWoodBasedBeam

材料木基梁：这是一个机械性能的集合，适用于木基材料的类梁产品，特别是层压材料，如集成材和LVL。这种材料的各向异性是根据晶粒方向和载荷类型的不同性质来考虑的。应根据当地设计规范给出标准化使用条件、标准化荷载持续时间和构件标准化参考尺寸的所有值。注：如果机械材料性能根据不同的给定参考尺寸进行分级，则每个要求的分级必须使用IfcExtendedMaterialProperties和IFCMatary的单独实例。机械上不同版本的材料被视为不同的材料。对纹理或排列方向的引用对应于由元素对象或类型的几何或拓扑表示给出的材料方向，特别是IfcMemberType和IfcStructuralMember。
