摘要
为了适应当前墙体改革和建筑节能的需要,对一种设有聚苯层的新型节能复合混凝土空心砌块墙体在竖向荷载作用下的力学性能进行了试验研究,考察了墙体的受力过程、开裂部位、裂缝发展情况、侧向挠度以及破坏形态,探讨了墙体尺寸以及不同构造措施对墙体受力性能的影响。研究结果表明,聚苯层能够为保护层提供有效的连结,墙体保护层没有发生脱落现象,水平拉结筋可以限制裂缝的开展,减小墙体的平面外变形,为这种新型节能复合混凝土空心砌块的推广应用提供依据。
The behavior of a new energy saving composite concrete hollow block masonry walls was researched in this paper. Based on the experimental study on three walls under compression, the deformation process, cracking load and ultimate load, destroy mechanism, vertical strain and failure mode were discussed. The influence of wall dimension and construction measures on the behavior of the specimens was studied too. Test result indicates that from beginning to the end, the out-side layer can connect to the wall well which shows that the benzenes can make efficient connection ensured the normal - working of the wall under vertical loading.
