[小记]金土木公司在2008年推出了CKS Detailer软件,帮助大家解决ETABS在工程上的应用问题。其实早在2007年4月,我在华工的高层建筑结构研究所就开发了类似的程序ETABS TO ENGINEER V1.0,当然比起专业公司当然是比较简单的。程序是内部使用,未商业化,做得比较粗糙,现简单介绍一下软件的功能,软件还在应不断的工程设计需求在不断更新的。
目前能够实现的功能有限,如打印ETABS的计算配筋量图纸,荷载图纸,模板构件尺寸图纸等。这些大大方便了在超限工程中的出图,平时只是PKPM的软件能出图,ETABS出图比较烦,现在有了DINOETE,可以像PKPM一样出图检查,打计算书。

【摘要】 中洲中心观光门架结构由相距120m的2个高86.5m的主塔楼和上下2个连廊组成,高空连廊跨度为120m,低空连廊跨度为90m。主塔楼采用带粘滞阻尼器的钢筋混凝土框架剪力墙结构,高空连廊采用带粘滞阻尼器的钢桁架结构,低空连廊采用纯钢桁架结构。该结构体形特殊,存在大跨度连体,刚度不连续等多项超限,结构的地震响应复杂。在小震和中震弹性分析基础上,采用基于纤维模型理论的PERFORM-3D软件对塔楼结构进行静力弹塑性分析,对整体结构进行大震动力弹塑性时程分析。并参考美国基于性能抗震规程ASCE-41制定构件变形性能指标,对构件的变形响应进行评估。小震和中震的结构弹性分析表明,结构与构件均满足规范要求。静力弹塑性分析结果与整体结构大震弹性算得的基底剪力作对比表明塔楼结构具有很好的抗侧性能。弹性分析以及弹塑性分析的计算结果对比表明分析结果合理,设置了粘滞阻尼器以后,构件非线性损伤减小,整体结构及构件满足既定的变形性能目标,且验证了设置阻尼器对结构抗震性能有着显著的提高效果
【英文摘要】 Abstract: The Zhongzhou sightseeing gate is composed of two 86.5m height towers which are linked by a higher corridor with a span of 120m, one at the top, and the lower corridor is with an at the height of 16.5m with an angle of 45 degree to the higher one. Frame-shear wall structure with viscous dampers is applied for the two towers, while steel structure with viscous dampers for the higher corridor and the pure steel structure for the lower one. The seismic behavior of the structure is complex due to the exceeding of several structural indexes from the limitation of current design code, such as long-span connected structure and abrupt change in stiffness etc. Based on elastic analysis under frequent and moderate earthquake action, static push-over analysis and inelastic time history analysis under rare earthquake are carried out with PERFORM-3D which is based on the fiber model. To evaluate deformation performance of the components, a guideline is proposed in this paper based on ASCE-41. The elastic analyses under frequent and moderate earthquake show that, the behavior of the whole structure and the components satisfy the code requirement. The comparison between the result of static nonlinear analysis and the base shear of the whole structure under rare earthquake indicate the lateral performance of the towers is well. The analysis result is reasonable by comparing the analysis of elastic and elastoplasticity. It can also be concluded that the damper can effectively improve the seismic performance of structures and the nonlinear damage of the components decrease. The deformation of whole structure and components satisfy the fixed goal and it is verified that the damper improved the seismic performance remarkably.
