对 8 4个高强混凝土空心砌块砌体的受压性能进行了试验研究·发现采用砌块强度≥MU15 ,砂浆强度≥M 10的砌体试件进行受压试验 ,利用砌体结构设计规范中的相关公式计算高强混凝土砌块砌体的抗压强度偏高 ,弹性模量偏小 ,不安全·说明规范公式已不适用于高强混凝土砌块砌体力学指标的计算·为此提出了计算高强混凝土砌块砌体力学性能指标的建议公式 ,经试验验证 ,计算值与试验结果符合得较好 ,且偏于安全·
The compression tests of 84 high-strength concrete hollow block masonry were carried out. It was found that the masonry specimens with block strength≥MU15 and mortar strength≥M 10 were subjected to compression test, and the masonry structure design code The formulas for calculating the mechanical properties of high strength concrete block masonry are not suitable for the calculation of mechanical indexes of high strength concrete block masonry. The formula of the mechanical properties of concrete block masonry is validated by the test and the calculated value is in good agreement with the test result and is biased towards safety
