Research work in this paper includes inelastic analysis of earthquake responses of single-story factory buildings with roofs continuing to act as a whole unit under seismic action. In case the building is made up of spans with roofs at different levels, then each roof system is taken as a horizontal rigid diaphragm with its mass concentrated at its center of gravity. Therefore, there are three degrees of freedom (two transla-tional and one rotational) corresponding to every mass.According to the above model,...

Research work in this paper includes inelastic analysis of earthquake responses of single-story factory buildings with roofs continuing to act as a whole unit under seismic action. In case the building is made up of spans with roofs at different levels, then each roof system is taken as a horizontal rigid diaphragm with its mass concentrated at its center of gravity. Therefore, there are three degrees of freedom (two transla-tional and one rotational) corresponding to every mass.According to the above model, a computer program was developed for the investigation of inelastic earthquake responses of equal-height or unequal-height multi-span single-story factory buildings subjected to ground motion in one or two directions.

The electronic structure of HFe3(CO)11-and its possible catalytic action in the carbonylation of propene have been studied by semi-empirical SCF method CNDO/2. In order to modify the convergency of calculation, a damping factor λwhich changes its magnitude during calculation was introduced into the CNDO/2 programme. Besides, a subroutine for computing two center energy EAB(A or B may be transition metal) was used. From the calculated energies of some intermediate state in the course of carbonylation of propene,...

The electronic structure of HFe3(CO)11-and its possible catalytic action in the carbonylation of propene have been studied by semi-empirical SCF method CNDO/2. In order to modify the convergency of calculation, a damping factor λwhich changes its magnitude during calculation was introduced into the CNDO/2 programme. Besides, a subroutine for computing two center energy EAB(A or B may be transition metal) was used. From the calculated energies of some intermediate state in the course of carbonylation of propene, the activation barrier of this catalytic reaction was estimated as 103 Kcal /mole, in another possible scheme, the activation energy of the carbonylation of propene to produce isobutanol was estimated as 233 Kcal/mole, which is much higher than the former. The charge transfer between the reactants and the catalyst in the course of reaction was also calculated. Discussion of the results was given.

本文采用CNDO/2(M)程序研究了三铁核羰基原子簇络合物HFe_3(CO)_(11)~-的电子结构,及其在丙烯羰基化过程中可能的催化作用。结果说明HFe3(CO)_(11)~-的桥键结构是稳定的,它具有催化活性,并且活性部位在桥键一湍,证实了内烯从桥端向催化剂进攻从能量上是有利的。通过计算说明HFe_3(CO)_(11)~-催化丙烯羰基化生成正丁醇的活化能高于生成异丁醇的活化能。上述结果均与郑作光等的实验结论一致。同时本文选择了一组适当的铁原子的参数,在改善计算收敛性等方面对原CNDO/2程序作了一定的改进。

In this paper the physical model of statistical treatments of random fatigue load has been discussed systematically, it includes the compressive approach to random load-time history, the detection of peak and valley values, the graphic model of rain-flow counting method, the counting conditions and the treatment of two dimensional random variable, through the investigation of statistical treatment to random load-time history by rain-flow counting method. This paper introduces the concept of convergent and divergent weves, and gives the calculating model of convergent and divergent waves of equivalent damage to the counting of second stage by rainflow counting method. The counting carries on until the end of load-time history record by rain-flow counting method, the calculating results coincide with entire closure of stress-strain hysteresis loop of material.The results of treatment may serve as the basis of fatigue load spectrum compilation for constant-mean-value, variable-mean-value and double-value methods and two dimensional random variable, and also appropriate to the estimation of fatigue life.

本文通过用雨流计数法对随机载荷时间历程统计处理程序的研究,系统地讨论了随机疲劳载荷的统计处理及其物理模型,其中包括对随机载荷时间历程的压缩处理,峰谷值的检测,雨流计数法的图解模型以及二维随机变量的统计处理等。文中引入了收敛发散波的概念,对雨流计数法的第二阶段计数给出了等效损伤收敛发散波的计数模型,继续用雨流计数法进行计数,计数结果与材料的应力-应变迟滞回线完全封闭相一致。 统计处理结果可作为常均值、变均值、双波法以及二维随机变量疲劳载荷谱的编制依据。同时也适用于疲劳寿命估算。
