【摘要】 进行了24个钢管橡胶混凝土轴心受压短柱的试验研究,基本力学参数为截面型式、橡胶粉掺量和橡胶粉粒径。本文研究目的在于:观察和分析钢管橡胶混凝土的破坏模态,研究其轴压力学性能,并采用辽宁省地方标准DB21/T1746-2009(2009)对钢管橡胶混凝土强度承载力进行计算。结果表明:(1)钢管橡胶混凝土具有较好的承载能力和延性;(2)规程DB21/T1746-2009(2009)计算结果与试验结果基本吻合。更多还原

【Abstract】 Twenty-four crumb rubber concrete-filled steel tubes subjected to axial compression are carried out.The main parameters varied in the tests are different sections,crumb rubber contents and size. An attempt is made to know difference of results by design codes DB21/T1746-2009(2009).The test results show that crumb rubber concrete-filled steel tubes have good bearing capacity and ductility.The result of DB21/T1746-2009(2009) is in agreement with that of the test.更多还原
