基于SAP2000 API的模态缩减法在高层建筑动力分析中的应用

为解决高层建筑自由度数目巨大导致其动力响应分析工作量大、效率低的弊端,文章在基于SAP2000API接口的基础上,分别运用原有结构整体刚度（静力凝聚法）和结构振型（SEREP法与MODAL法）3种不同方法,对高层建筑建立了简化为“葫芦串”体系的模态缩减方法.算例计算表明,直接基于原有结构整体刚度的模态缩减方法,对于结构的前几阶振型,具有较高的模拟精度；而基于结构振型的模态缩减方法（SEREP法与MO-DAL法）在所取的振型阶数范围内,能够完全一致地保留原结构的振动特性；而在所取的振型阶数范围外,相比于SEREP法,MODAL法能够大致反映结构的振动情况.由于对高层建筑动力分析通常只考虑前几阶模态的情况,文章结合SAT2000 API应用程序接口的功能,应用上述3种模态缩减方法,为自动化和高效化地实现高层建筑动力分析提供了良好的条件.     

Testing and Modeling for Energy Dissipation Behavior of Velocity and Displacement Dependent Hydraulic Damper

A passive energy-dissipating device, velocity, and displacement dependent hydraulic damper (VDHD), is developed to reduce the seismic response of structure. This device is comprised of a hydraulic jack, check valve, relief valve, and throttle valve. The numerical analysis model for SAP2000 nonlinear analysis program is proposed to simulate the energy-dissipating characteristics of VDHD. The analysis results of this model compared with the seismic resistant tests reveal that this proposed model can accurately describe the actual energy-dissipating behavior of VDHD. The efficiency of VDHD is confirmed using this proposed model for carrying out numerical analyses of bare building, building added with bulking resistant bracing (BBR), and VDHD. The energy-dissipating capabilities of VDHD are performing excellent displacement and acceleration control with various ground magnitudes; being an energy absorber to absorb mechanical energy in the structure and resist structural movement; and gathering the advantage of BRB.     

Application of thiophilic chromatography to deplete serum immunoglobulins in sample preparation for bidimensional electrophoresis

Serum is a typical sample for non-invasive studies in clinical research. Its proteome characterization is challenging, since requires extensive protein depletion. Methods used nowadays for removal of high-abundance proteins are expensive or show quite often a low loading capacity, which has strong repercussions on the number of samples and replicates per analysis.In order to deplete immunoglobulins (Igs) and albumin (HSA) from 1 mL serum samples, we have developed a protocol based on a combination of thiophilic chromatography, not previously used in clinical proteomics, and a HSA-specific resin. Ig/HSA-depleted samples, immunoglobulinome and albuminone were analyzed by 2-DE. Thiophilic chromatography, coupled with HSA-depletion, allows a good 2-DE resolution as well as the visualization of new spots. Moreover, it yields enough protein to evaluate technical variability and facilitate subsequent protein identification. To validate the protocol, we carried out a preliminary comparative study between triplicate Igs/HSA-depleted serum samples from healthy control individuals and recently diagnosed/untreated rheumatoid arthritis (RA) patients. RA patients showed several acute phase proteins, as well as additional serum proteins, differentially and significantly regulated.Therefore, thiophilic chromatography can be used as an efficient and economical method in 2-DE to deplete immunoglobulins from large human serum samples before a more extensive fractioning.

基于地震损伤次生火灾概率研究

地震的发生会破坏原有的自然平衡和社会稳定,易引起一系列二次破坏,这种破坏在空间上和时间上可能比地震本身更具危害性.其中,火灾是建筑物主要面临的地震次生灾害之一.云南大学新校区地处昆明市呈贡区,位于小江断裂带和普渡河断裂带之间,属地震多发区,且学校内部建有化学实验室和食堂,地震发生后极易引发次生火灾.为了研究校园区域地震次生火灾的发生率,通过MATLAB程序调用SAP2000对一幢RC框架结构进行非线性时程分析,基于Park-Ang双参数损伤模型求解结构在不同强度等级地震作用下的损伤D值,并结合实地调研构建适用于不同使用功能建筑的次生火灾起火概率模型,为云南大学震后火灾救援工作和基于性能的抗震防火设计提供参考.
