| 摘 要： | 为研究蒸压粉煤灰砖砌体受压变形性能,以砂浆强度为主要参数,对18个蒸压粉煤灰实心砖砌体试件及15个普通粘土砖砌体试件进行轴心受压试验,对试件的受力状况及其应力-应变关系进行分析研究。试验表明,蒸压粉煤灰砖砌体弹性模量值低于普通粘土砖值且实测值高于规范值。弹性模量随荷载增大有明显降低,且有较强的非线性特征。泊松比实测值与普通粘土砖值相近。给出蒸压粉煤灰砖砌体的应力-应变关系表达式及其弹性模量、泊松比的建议计算公式。

| Abstract: | To study the compressional deformation performance for autoclaved fly ash brick masonry,axis compression tests were conducted on 18 autoclaved fly ash brick masonry samples and 15 common clay brick masonry samples.Load and stress-strain relationship are analyzed.The experimental results indicate that measured elastic modulus values of autoclaved fly ash brick masonry are lower than clay brick masonry's and higher than standard value.Elastic modulus decreases significantly as load increases and there is nonl... |
