Abstract In order to realize the directional and controllable splitting of splitting grouting, the field grouting test was carried out. Using a new grouting pipe designed, the splitting direction and size of the branch vein are effectively controlled through the control of grouting pressure and grouting amount. In order to explore the bearing characteristics of split grouting pile and provide necessary parameters for the design of split grouting pile composite foundation in engineering practice, the field static load test and indoor geotechnical test of split grouting pile are designed, and the ultimate bearing capacity of single pile and necessary soil parameters are obtained. In order to make up for the limitations of field static load test, the three-dimensional finite element model of pile, soil and branch vein of split grouting pile is established by using the finite element analysis software ABAQUS. The finite element analysis results are compared with the measured values of field test, and the variation laws of pile shaft axial force, stress and displacement of branch vein at different depths, pile side friction, etc. are further explored, Through these changes, the interaction and load transfer mechanism between pile and soil are analyzed, which provides a reference for optimal design.

This study focuses on test loading program and evaluation for pedestrian bridge. On the basis of the finite element analysis, numerical model of Lv River Bridge, which is a steel box pedestrian suspension bridge, is established. Moreover, field static load test is done and the results of tests are compared to the theoretical values. Results show that the measured result fits well with the theoretical result and bridge is in the situation of elastic deformation, and the strength and stiffness satisfy the need of design.

In order to study the basic mechanical property of cast-in-place stiffening-ribbed-hollow-pipe reinforced concrete girderless floor, and similarities and differences of the structural performance compared with traditional floor, we carried out the destructive stage loading test on the short-term load test of floor model with four clamped edges supported in large scale, and conducted the long-term static load test. Also, the thesis conducted finite element analysis in virtue of ANSYS software for solid slab floor, stiffening-ribbed-hollow-pipe floor and tubular floor. The experiment indicates that the developing process of cracks, distribution and failure mode in stiffening-ribbed-hollow-pipe floor are similar to that of solid girderless floor, and that this kind of floor has higher bearing capacity and better plastic deformation capacity. The finite element analysis manifests that, compared with solid slab floor, the deadweight of stiffening-ribbed-hollow-pipe floor decreases on greater level while deformation increases little, and that compared with tubular floor, this floor has higher rigidity. So stiffening-ribbed-hollow-pipe reinforced concrete girderless floor is particularly suitable for long-span and large-bay building structure.

In this paper, the application of finite element software with the actual structure of the field static load test for the engineering background, describes the space effect of portal frame under vertical load. Established a gymnasium mode of portal frame through the finite element software, quantitative analysis the space effect under the vertical load, and studied the spatial interaction of longitudinal anti-lateral component to the overall structure, and compared with the results of the field static load test. The calculation results show that, the reduction of spatial effect to internal forces under the vertical load should be considered in design. It is important that a reasonable increase in rigid tie and support can enhance the space effect of the whole portal frame.

An experimental study on material characterization of SMC (Sheet Molding Compounds) compression molded parts was carried out by 3-point bending tests and creep tests. And computer simulation of optimum condition of SMC design was carried out by finite element analysis. The thicknesses of SMC specimen were 6.5, 7, 7.5 and 8mm and the angles of inclination were 0°, 2.5°, 5°, 7.5° and 10°. After static load test, the stress of SMC was different at the each condition. The influence of angles of inclination was important. The maximum stress occurred at 0°. But the more angle of inclination was big, the more maximum stress was small. The decrement was big at the range of 0° to 2.5°. The influence of thicknesses also was important. The more thickness was large, the more maximum stress was small.

The stress behavior of the reinforced inorganic polymer concrete(IPC) beam was discussed, included the load-deflection curve, craze load and ultimate bearing capacity under the static load function through the method of the experimental study and the non-linear finite element analysis. Compared the data of the experiment with the results of the finite element analysis, it indicates that the reinforced IPC beam owns higher ductility ratio and better deformation capacity on the same loading condition. Meanwhile, the cracks of IPC beam develop more slowly than the normal ones, there were less and smaller cracks on IPC beam. The research results offer the theoretical and experimental references for engineering practice and design index of IPC.

Through the measured simply supported bridge's dynamic parameters, we can establish the finite element model of the structure.As the flexibility matrix can reflect the actual state of the bridge, making the actual measured flexibility matrix as a basis to inverse the bridge’s finite element model .Combined with the engineering practice static load test, we can assess the bearing capacity of the bridge according to inversion model bridge.

Finite element analysis (FEA) is used, with increasing frequency, to supplement or justify the design of an ASME Section VIII, Division 1 or 2 pressure vessel. When this occurs, good engineering practice indicates that a competent engineer should review the finite element analysis report. In some jurisdictions, it is required that a Professional Engineer review and certify the report. This paper discusses some of the practical aspects of both writing and reviewing a good quality FEA report — both in the context of the technical perspective and in the context of Code compliance. This paper will serve as a practical assistant to an engineer reviewing an FEA report, as well as a guide to an engineer preparing an FEA report. Aspects such as properly following Code requirements, following appropriate Design By Analysis methodologies, and applying good design practices will be discussed.
