[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。

今年六月份,高层与特种结构设设计《The Structural Design of Tall and Special Buildings》发表了我的两篇论文,分别是:Seismic performance analysis of Wenchuan Hospital structure with viscous dampers Research summary on long-span connected tall building structure with viscous dampers
两篇论文讲述我们的基于性能抗震设计方法与结构弹塑性分析手段在粘滞阻尼器结构中的应用,一个是汶川医院,另一个是广州中洲中心二期的项目。内容比较多,包括了PERFORM-3D的前后处理ETP的开发成果,风振时程分析方法的研究,整体结构几何非线性的简化计算等。特别是中洲中心的论文,得到审稿专家,美国高层结构专家Gary Hart教授的好评,并获推荐特刊发表。以下是这两篇论文的摘要。《The Structural Design of Tall and Special Buildings》虽然因子不高,但是很多工程实例与工程分析处理方法上,是一本很值得看的刊物。

Abstract
The HUB-Sightseeing Gate in Guangzhou, which is a connected tall building structure, is composed of two main frame-shear wall towers, which are 86·5 m high, and two steel galleries at top and bottom, respectively. The top gallery is a 120 m long-span steel truss. Vicious dampers are set in the two main towers and the top gallery. It is an ultra-limit structure with complicated structural shape and hybrid structure system. Design idea of performance-based seismic design is presented in this paper. Seismic performance of the structure under different levels of ground motion is analysed and verified by different methods, such as elastic analysis under frequent earthquake, unyielding and elastic check of structure element under medium earthquake and inelastic dynamic time history analysis under rare earthquake. Taking the result of shaking table test as a reference, reasonable enhanced measures of seismic design are suggested. Meanwhile, wind-induced vibration time history analysis under different directions based on wind tunnel test is applied in this paper, and comfortableness problem can be well resolved. The control effects of vicious dampers on internal force, deformation, acceleration and energy dissipation of the structure are also studied. By means of the analysis methods mentioned above, and other analyses such as whole structure stability, temperature effect, floor vibration and so on, relevant measures of ultra-limit structure design are suggested, and the performance objective of the structure can be well realized.

Abstract
Analytical investigation was undertaken to assess the seismic performance of Wenchuan Hospital located in Wenchuan county, southwest China's Sichuan province, where a severe earthquake has occurred in May 2008. The structure consists of a four-storey reinforced concrete frame with viscous dampers. The irregular building is 18·35-m tall and has a total floor area of 17 000 m2. Viscous dampers are set along the outside surface of structure to get a more efficient reduction of structure responses. The design idea of performance-based seismic design is presented in this paper. Seismic performance of the structure with and without viscous dampers under different levels of ground motion is analysed and verified by different methods, including elastic analysis under frequent earthquake, unyielding and elastic check of structure element under medium earthquake, static nonlinear analysis and dynamic nonlinear analysis under rare earthquake. And a comparative analysis is presented, such as results between elastic and inelastic analysis, static nonlinear analysis and dynamic nonlinear analysis, and structure with and without viscous dampers. The control effects of viscous dampers on internal force, deformation and energy dissipation of the structure are also studied. Meanwhile, a practical method to calculate the supplemental damping ratio added by viscous dampers is proposed for elastic analysis with dampers. After a series of analysis, the performance objective of the structure can be well verified.
