［摘要］通過改變混凝土普通磚和砂漿的強度等級，研究了混凝土普通磚砌體的軸心抗壓和雙面抗剪的力學性能和破壞特征，分析了混凝土普通磚砌體的抗壓和抗剪強度及其影響因素。根據(jù)試驗數(shù)據(jù)回歸得出了混凝土普通磚砌體的抗壓強度和抗剪強度的建議計算公式，并繪制了混凝土普通磚砌體的抗壓應力應變關系曲線。試驗結果表明，混凝土普通磚砌體的抗壓強度及抗剪強度均高于同強度等級的實心黏土磚，其受力特點與破壞形態(tài)與實心黏土磚相近，可以作為替代實心黏土磚的新型承重墻體材料之一。

［關鍵詞］混凝土普通磚；抗壓強度；抗剪強度；應力-應變曲線

Abstract:By changing the intensity grades of concrete common brick and mortar, the mechanical performance and failure characteristics about the axial resisting pressure and double resisting shear are researched, and the influence factors are analyzed in detail. Based on the experimental dates, the compressive strength and the shear strength advised formulas of concrete common brick masonry are proposed, and the stress-strain curve is plotted. It is implied in the experimental result that the compressive strength and the shear strength in concrete common brick masonry are higher than those of fired common brick masonry at the same grade, however, the mechanical performance and failure characteristics are the same. So the concrete common brick masonry can be used as the new load-bearing wall material instead of fired common brick masonry.

Keywords:concrete common brick masonry; compressive strength; shear strength; stress-strain curve
