To investigate the seismic behavior of specially shaped column joints with X-shaped reinforcement,two groups of specimens with or without X-shaped reinforcement in joint core region were tested under constant axial compression load and low reversed cyclic loading,which imitated low to moderate earthquake force.The seismic behavior of specially shaped column joints with X-shaped reinforcement in terms of bearing capacity,displacement,ductility,hysteretic curve,stiffness degradation and energy dissipation was studied and compared to that without Xshaped reinforcement in joint core region.With the damage estimation model,the accumulated damage was analyzed.The shearing capacity formula of specially shaped column joints reinforced by X-shaped reinforcement was proposed with a simple form.The test results show that X-shaped reinforcement is an effective measure for improving the seismic behavior of specially shaped column joints including deformation behavior,ductility and hysteretic characteristic.All specimens were damaged with gradual stiffness degeneration.In addition,X-shaped reinforcement in the joint core region is an effective way to lighten the degree of cumulated damage.The good seismic performance obtained from the specially shaped column joint with X-shaped reinforcement can be used in engineering applications.The test value is higher than the calculated value,which indicates that the formula is safe for the design of specially shaped column joints. 相似文献

高中数学有着较强的抽象性与逻辑性,传统的灌输式课堂导致学生兴趣缺乏、自主学习能力缺失,课堂教学质量难以保障.因此,教师应结合新课改要求,创新课堂教学模式,科学设计教学内容,并提高训练题内容的针对性,加深学生对理论知识的理解程度,潜移默化地提高学生的自主学习能力.基于此,文章分析了培养高中生自主学习能力的意义,结合高中数学课程教学案例提出了培养学生自主学习能力的策略,以期为相关从业人员提供一点参考. 相似文献
