Analysis of High Span Curved Net Frame Lifting

A proposed dry coal shed grid plan size is 99m*140m, through the establishment of structural model, using Midas Gen finite element analysis software for structural verification and analysis, and finally determine the best construction plan.

Analysis and Application of Shock Absorption Measures for High-rise Inpatient Building of a Hospital in High Intensity Fortification Area

A proposed 22-storey hospital building is located in an area with 8-degree seismic fortification and is a reinforced concrete frame-shear wall structure. Through the establishment of structural model, calculation and comparative analysis are carried out by using ETBAS and PERFORM-3D software. The viscous damping wall is used for energy dissipation and damping, and the optimal damping scheme is determined by multi round time history analysis and optimal adjustment of the number and location of dampers.

The Integrative Establishment of a Three-Dimensional Structure Model of Changling Gas Field in Changling Fault Depression

The three-dimensional (3D) geological modeling technique which is considered as an important skill of fine reservoir description has been gaining more and more attention. On one hand, it can efficiently promote the transformation of reservoir description from two-dimensional (2D) to 3D, and from qualification to quantification as well. The 3D reservoir geological model can be used as basic geological knowledge in terms of adjusting well patterns and indicating remaining oil distribution, through reflecting the spatial distribution characteristics and the variation of the reservoir physical property. On the other hand, the 3D modeling technique specializes in the representation of local micro features in comparison of regular ways. This article aims at subtly describing the structural modeling of Changling gas field of Changling fault depression. The result of this case study shows that the establishment of structural model is consistent with the understanding of fault development which was proved during the process of producing gas, thus the structural model has high reliability. Therefore, the structural model is of great guiding significance for the design of new well and the well patter optimization.

Modal Parameter Extraction of a Turboset From High Speed Balance Data

Turbosets used in power generation industry are frequently placed on flexible foundations, which significantly influence the overall dynamics. Establishment of structural models that capture the rotor and foundation effects reliably using finite element modeling or modal analysis is difficult because of model complexity and/or costs involved. This paper presents a method to extract modal parameter information of a turboset using frequency response function data recorded during high speed balancing. The main advantage of the present method over the others is the low cost and small effort involved, so that it is of practical use in an industrial setting. A real life example dealing with parameter extraction for a large generator rotor is presented to demonstrate its implementation.
