Finite element modelling of plate girders with web openings

This paper is concerned with a finite element model to predict the behaviour and ultimate load of plate girders with web openings. The finite element package is used to model the plate girders with web openings. Accuracy of the model is assessed by applying it to plate girders tested earlier by other researchers. Comparison of analytical results with the available experimental results for yielding patterns, ultimate load values and load–deflection relationships show good agreement between the finite element and experimental results thus validating the accuracy of the proposed model. The proposed finite element method was extended to carry out a parametric study. The study covered parameters such as web slenderness and flange stiffness.     

Design Water Levels in Tidal River Systems under the Influence of Typhoons

Water levels in tidal rivers are subject to the influence of both fluvial and tidal factors. The interaction between these factors is rendered more complex in regions affected by typhoons, which typically result in the combined occurrence of heavy rainfall and high sea levels.
Previous studies have outlined an analytical approach for calculating design water levels based on dividing the fluvial and tidal series into a typhoon and a non-typhoon component. This paper illustrates the steps involved in the analytical approach and describes its application to drainage basins in Hong Kong.
The approach provides a practical means for calculating design water levels, and is recommended for final design purposes. The results of using the full analysis may be approximated by using a sub-set of analytical results, and should prove satisfactory for the purposes of outline design.

Dynamic analysis of viscoelastic structures using incremental finite element method

This paper presents an efficient and accurate incremental finite element procedure, without involving any integral transformations, to deal with practical viscoelastic structures with complicated geometries subjected to dynamic loadings. The numerical error induced from the approximate inversion technique used is thus avoided. Based on the Hamilton's variational principle, an incremental functional is derived for each time increment and the inertia terms are retained in the analysis to estimate the transient viscoelastic behaviours. To model the specific stress-strain-time constitutive behaviours of viscoelastic materials, the Norton type time hardening rule is employed. In the present computation procedure, the change of creep strains is regarded as increments of fictitious body forces at the nodal points for the next time increment.

To evaluate the accuracy and the versatility of the solution technique developed in this work, several examples are given.

营改增后水电工程简易计税项目税金计算研究

营改增全面落地与实施后,大中型水电工程因建设周期较长,导致大量项目跨越营业税和增值税两种主体税。在营业税和增值税两种税制下,项目计价方式存在一定差异,导致税金计算方式有所不同。通过对营改增后适用简易计税项目税金计算方式的研究,得出结论:营改增后水电工程中适用简易计税的项目缴纳税金将有所减少,建设单位在对承包人结算工程款时需要扣减税金差值。

辐射、对流和导热的联合模拟方法在建筑中庭空调系统设计中的应用

对于具有大面积玻璃围护结构的建筑中庭，由于太阳辐射强、室内空间大等问题，导致热环境的控制非常复杂。对于这类建筑的空调系统设计，计算流体力学（CFD）等数值模拟方法的应用有着广阔的发展前景，但已有的数值计算方法复杂，通用性差，仅能被少数计算流体力学领域专业研究人员所掌握，这一因素大大制约了数值模拟方法的在实际工程中的广泛应用。本文对相关数值模拟方法进行了分析和总结，建立了一套简单快速的并具有合理准确性的通用联合模拟方法，并开发出相应的联合模拟计算程序。通过将模拟计算结果与实验结果进行比较，该方法的准确性得到了验证，同时将该方法应用于中庭空调系统的优化设计，表明了其在实际工程应用中的可行性。
