Xtract CAD复杂截面建模小工具
Xtract 是一个非常好的截面分析程序,如果支持国产也可以使用Dino开发DinoSec快速截面分析程序。Xtract更适合于建立非常复杂的组合截面,如果建立复杂截面,推荐使用该项程序,该程序是CAD为基础,建立复杂的构件截面,包括巨型柱及复杂的桥梁截面,该程序需要使用AUTOCAD2013版程序,程序请自行下载。

DINOSEC截面分析程序使用手册
1)程序介绍:
DINOSEC截面分析程序是基于平截面假定,对常用组合截面进行承载力的计算,通过计算得到主轴的PMM曲线或指定轴力的Mx-My相关曲线,PMM曲线对构件的承载力设计具有指导意义。DINOSEC的输入与输出十分便利,可快速用于工程设计。 计算主要原理如下:
(1)采用平截面假定,应变分布为平面方程。
(2)截面分析采用纤维单元法,即将混凝土与钢材离散为纤维。
(3)迭代分析采用二分法逼近求解。
(4)通过洞口(负应力)纤维考虑纤维重叠的影响,如叠合柱的计算中已考虑

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.
