摘　　要：【目的】为了研究一种多功能实心区域的预制高性能混凝土夹芯外挂墙板的抗弯性能。【方法】利用有限元模拟软件ABAQUS建立试件的有限元模型,并讨论混凝土强度、内外叶板厚度、钢筋间距、钢筋强度对抗弯性能的影响。【结果】结果表明:该新型墙板具有良好的刚性和延性,模拟过程中最大应力部分出现在荷载加载点的纯弯段区域;在总厚度不变的情况下,混凝土强度、内外叶板厚度能明显提高其承载能力;钢筋间距、钢筋强度对承载力基本没有影响。【结论】综上所述,该类型墙板抗弯性能良好,能满足安全使用要求,在实际工程中可以通过提升混凝土强度、内外叶板厚度来获得更加优异的抗弯性能。[Purposes]To investigate the flexural performance of a prefabricated high performance con-crete sandwich external wall panel with a multifunctional solid zone.[Methods]A finite element model of the specimen was established using the finite element simulation software ABAQUS,and the effects of concrete strength,inner and outer leaf plate thickness,reinforcement spacing,and reinforcement strength on flexural performance are discussed.[Findings]The results show that:the new wall panel has good ri-gidity and ductility,and the maximum stress partly appears in the pure bending section region at the load loading point during the simulation;the concrete strength,inner and outer leaf plate thickness can signifi-cantly improve its load bearing capacity under the condition that the total thickness remains unchanged;the reinforcement spacing and reinforcement strength basically have no effect on the load bearing capac-ity.[Conclusions]In summary,this type of wall panel has good flexural performance and can meet the requirements for safe use.In practical engineering,the concrete strength and thickness of the inner and outer leaf panels can be increased to obtain more excellent flexural performance.
