【摘要】 蒸压粉煤灰砖属于可以替代烧结普通砖的新型墙体材料,提高蒸压粉煤灰砖砌体的抗剪性能是改善此类砌体结构抗震、抗裂能力的关键。带肋蒸压粉煤灰砖通过改善砖的外形,在砖的表面开槽形成肋状,可提高砖砌体的抗剪能力。本文对带肋蒸压粉煤灰砖砌体、普通蒸压粉煤灰砖砌体和烧结普通砖砌体的抗剪性能进行了比较研究,并结合相关规范条文探讨了带肋蒸压粉煤灰砖的有关抗震、抗裂措施,为蒸压粉煤灰砖在地处地震高发区同时具备气候干燥,年温差、日温差大的新疆地区推广应用提供理论依据。更多还原

【Abstract】 Autoclaved fly ash brick is classified as one new wall material to replace fired brick,promoting the shear property of autoclaved fly ash brick masonry is very important for improving the earthquake resistance and crack resistance of masonry structure.Because of fluting the surface of brick,the shear property of ribbed autoclaved fly ash brick masonry would be improved.In the paper,the shear property of ribbed autoclaved fly ash brick masonry,common autoclaved fly ash brick masonry and fired brick have been comparative studied,and the earthquake resistance and crack resistance measures have been discussed under the premise of relative standard citations,in order to provide the theoretical basis for autoclaved fly ash brick’s further promotion and application in Xinjiang which is located in seismic high-incidence area,while have climate characteristics of dry climate,high annual temperature difference,high diurnal temperature difference.更多还原
