Progressive collapse analysis of reinforced concrete frame structure and fortification criterion

为了提高建筑抵抗连续倒塌的能力，从2008年开始，我国修订的工程结构设计规范中，相继提出了防连续倒塌的设计原则，且正在编写防倒塌设计规程［44］。本文基于文献［44］给出的防倒塌设计方法，对一栋六层钢筋混凝土框架结构，在不同柱网布置、不同抗震设防烈度下的结构进行防倒塌设计，结果表明，若采用拆除构件法，绝大部分水平构件均无法满足防倒塌设计的要求，满足防倒塌设计的水平构件用钢量需增加12%～480%。若采用局部加强法，则几乎所有的柱均可满足防倒塌设计的要求。文中还编制了拆除构件法中的梁铰机制、悬索机制，以及局部加强法中柱弯矩的设计用表，为工程设计提供参考。 在上述算例设计分析的基础上，文中认为防...In order to improve the ability of progressive collapse, from 2008, our country successively put forward the design principle of progressive collapse in the revision of the engineering structure design specification[44] and compile progressive collapse resistance design code.

Study on kinetics of propylene polymerizationat different temperatures via Monte Carlo simulation

在不考虑其他杂质参与聚合反应的情况下,并基于已有对丙烯聚合反应过程的普适化认识,提出了一个普适的丙烯聚合反应机理(基元反应).在已有的丙烯聚合反应机理基础上,为了证实该聚合反应过程总活性基是否满足“稳态假定”以及考察聚合反应温度对聚合过程的影响,采用蒙特卡罗模拟方法研究了传统Ziegler-Natta催化剂催化下的丙烯聚合动力学.模拟得到的总活性基数目在丙烯聚合初期快速增加到峰值,然后随聚合反应的进行保持恒定,证实了丙烯聚合过程中总活性基符合稳态假定.同时,模拟得到了聚合温度对丙烯聚合过程的转化率、分子量的影响.模拟结果表明:在聚合过程中,丙烯单体的消耗速率随聚合温度升高而增加;不同聚合温度下的数均聚合度峰值相同,但随温度增加,数均聚合度峰值来得早;随聚合温度增加,数均分子量减少,分子量分布变宽.The elementary reactions of propylene polymerization catalyzed by conventional Ziegler-Natta catalysts was proposed according to the comprehensive view and without considering the effect of any impurity in the material on propylene polymerization.The Monte Carlo simulation technique was employed to investigate the kinetics of propylene polymerization in order to determine the validity of the stationary state assumption and the effects of the polymerization temperature on the polymerization.The simulated total amount of active species,which only increases quickly at the beginning of the polymerization,indicates that the stationary state assumption in the studied system is valid.Moreover,significant effects of polymerization temperature on the polymerization conversion,and the molecular weight and its distribution were also analyzed.The simulated results show that the consumption rate of propylene increases with the increase of polymerization temperature;the maximum values of the number-average degree of polymerization are constant at different polymerization temperatures,however,the peak appears earlier with the higher temperature;as the polymerization temperature increases,the average molecular weight decreases and the molecular weight distribution changes greatly.The National Natural Science Foundation of China(No.20406016);; the Project of Fujian Petrochemical Company of SIN-OPEC (No.MS/FJ-08-JS-15-2005-01)

神经网络偏最小二乘法 (NNPLS)被应用于一种甲烷氧化偶联多组分催化剂的鲁棒反应模型的建立 .重点研究了内层神经网络学习算法、激活函数、网络结构 (包括隐含节点数、隐含层 )、网络权值初始化及主元的选取原则等 .研究表明 ,内层神经网络分别采用 1 10 5 1,1 8 4 1,1 8 5 1,1 7 4 1,1 8 4 1,1 8 6 1的拓扑结构是合适的 ;Levenberg Marquardt方法被用于网络的学习算法可以加快学习速度 ;同时采用了sigmoid函数为激活函数 .计算结果显示 ,四主元可以满足建模的需要 .与单纯的神经网络催化剂模型相比 ,NNPLS方法压缩分解了变量 ,减少了计算量 ,同时使模型的推广能力得到提高 ,有效地改善了直接神经网络建模过程中催化剂模型泛化能力较差的缺点 .In this paper neural network partial least square (NNPLS) was used to establish a robust reaction model for a multi-component catalyst of methane oxidative coupling. The details, including the learning algorithm, the number of hidden units of the inner network, activation function, initialization of the network weights and the principal components, are discussed. The results show that the structural organizations of inner neural network are 1-10-5-1, 1-8-4-1, 1-8-5-1, 1-7-4-1, 1-8-4-1, 1-8-6-1, respectively. The Levenberg-Marquardt method was used in the learning algorithm, and the central sigmoidal function is the activation function. Calculation results show that four principal components are convenient in the use of the multi-component catalyst modeling of methane oxidative coupling. Therefore a robust reaction model expressed by NNPLS succeeds in correlating the relations between elements in catalyst and catalytic reaction results. Compared with the direct network modeling, NNPLS model can be adjusted by experimental data conveniently and the calculation of the model is simpler and faster than that of the direct network model
