【摘要】 为了研究实腹式钢骨混凝土异形柱在偏心荷载下的破坏机理、受力性能及变形能力。本文通过对12个十字形钢骨混凝土异形柱进行偏心受压承载力的试验研究,观察了含钢率和偏心距不同情况下的试件受力过程和破坏形态,分析了钢骨混凝土异形柱的荷载-位移曲线、承载力、位移延性等力学性能。通过试验,明确了钢骨混凝土异形柱的破坏特征,含钢率对承载力的影响。试验结果表明,含钢率越大,构件的承载力及延性也会相应增加,钢骨混凝土异形柱具有较高的承载能力和较好的延性。更多还原

【Abstract】 A new type solid-web steel reinforced concrete special-shaped columns have been designed.In order to get the failure mechanism and capacity of solid-web steel reinforced concrete special-shaped column,testing studies of 12 specimens are made to investigate the bearing capacity,the failure process and modes.The failure characteristics,mechanical behaviors of the eccentrically compressed steel reinforced concrete special-shaped columns such as the loading-displacement and skeleton curves,load bearing capacity,displacement ductility are analyzed.Through the experiments,we can know the damage features of steel reinforced concrete special-shaped columns and the effect on steel ratio carrying capacity and ductility.It is concluded that,steel reinforced concrete special-shaped columns have high load bearing capacity and excellent ductility,the new type solid-web steel reinforced concrete special-shaped column can be used in engineering projects widely.更多还原
