摘要
目的研究蒸压粉煤灰实心砖墙体抗震性能、破坏形态和设计方法,为编制蒸压粉煤灰砖建筑技术规程提供依据.方法试验利用沈阳建筑大学结构工程实验室的建研式加载装置,采用拟静力试验方法对3片不同试验参数的蒸压粉煤灰砖墙体进行了破坏性试验.结果本次试验的试件抗剪承载力实测值与《建筑抗震设计规范》的抗震抗剪承载力计算值的平均值之比为3.63,说明规范取值较保守.结论鉴于本次试验试件数量较少,建议蒸压粉煤灰实心砖砌体抗震抗剪承载力仍按《建筑抗震设计规范》中抗震抗剪承载力计算公式计算,所给的结论和设计建议可供编制蒸压粉煤灰砖建筑技术规程参考.
Study on seismic behavior of autoclaved fly ash brick masonry wall,failure mode and design method,provides a basis of order for the preparation of autoclaved fly ash brick building technology.Experiment,with the construction of Shenyang Jianzhu University of structural engineering research laboratory built loading device type,is carried out by pseudo-static test methods on three different parameters of autoclaved fly ash brick wall destructive testing.The test specimens measured shear strength values and the＂Seismic De-sign of Buildings＂of the seismic shear strength calculated the average ratio of 3.63,indicating a more con-servative standard values.Because the number of specimen is limited,seismic autoclaved flyash solid brick masonry shear capacity based upon the＂Seismic Design of Buildings＂in seismic shear strength calculation formula is still recommended.The conclusions and design proposals of this paper could be taken as reference for the preparation of autoclaved fly ash brick building technical regulations.
