对泡沫钢的结构应用、制作、属性及模拟方法进行说明。泡沫钢内部含有许多微小空隙,故提出紧密度,作为泡沫钢的设计变量。改变紧密度,泡沫钢结构的工程特性可能发生重大变化:质量与刚度之比显著提高,有效能耗和热电阻也发生较大变化。在土木工程领域中,泡沫钢的实际应用尚未见报道。因此,在类似结构研究比较充分的前提下,着重研究现有泡沫钢的理论或泡沫铝的实际应用。泡沫钢的应用取决于制作方法,特别是成本费用及泡沫钢的性能。总结了已公开的泡沫钢生产方法、结构属性(模态、屈服应力等)或非结构属性(导热性、隔音性)。总结了泡沫钢属性的现有测量模型,突出了材料紧密度的重要作用。现有研究证明了泡沫钢在结构工程应用中的有效性,并指出进一步的研究方向。
The structure of foam steel applications, production, properties and simulation methods are described. Foam steel contains many small internal space, it proposed the tightness, as the design variables of foam steel. To change the tightness, the structural characteristics of the foam steel structure may change significantly: the ratio of mass to rigidity increases significantly, and the effective energy consumption and thermal resistance also change greatly. In the field of civil engineering, the actual application of foam steel has not been reported yet. Therefore, under the premise of similar structure research, the emphasis is put on the theory of existing foam steel or the practical application of aluminum foam. The application of foam steel depends on the method of manufacture, especially the cost and the performance of the foam steel. Disclosure of the disclosed foam steel production methods, structural properties (modal, yield stress, etc.) or non-structural properties (thermal conductivity, sound insulation) are summarized. The existing measurement models for the properties of foam steel are summarized, highlighting the important role of material tightness. Existing research proves the effectiveness of foam steel in structural engineering applications and points out further research directions.
