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.

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.

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.

Taking structure strengthen of a large hotel as the engineering background, based on superposition principle, put forward the design method of concrete two-way slab strengthened with partially bonded steel plate. According to the finite element analysis, the solid finite element model is established, and then the stress, strain and deflection of two-way slab strengthened with bonded steel plate is obtained, at the meantime compared with the load test datum in situ. The analysis results show that the finite element software is a reliable tool applied to analyze the design of two-way slab strengthened with bonded steel plate. When the increasing load is larger, partially bonding steel plate strengthening has more advantage and economize than bonding carbon fiber strengthening on two-way slab, meanwhile that slab strengthened with partially bonded steel plate has better mechanical properties, strength and stiffness.

This paper describes a numerical thermo-mechanical model for concrete pavement, implemented in OOFEM software. The thermal part is a heat transfer problem with appropriate initial and boundary conditions (sun irradiation, radiation and convection), calibrated from experimental data. Heat release from cement hydration is also included, calibrated for commonly used cements to demonstrate the difference that can be achieved with the binder selection. The mechanical part of the problem is composed of a 3D elastic concrete slab, subsoil Winkler-Pasternak elements and 1D interface elements, allowing separation in tension. The Winkler-Pasternak constants C1 and C2 were firstly determined from TP170 document and refined later from static load tests on the highway. The model validates well temperature field, static load test and provide several useful insight such as feasible time for summer casting, stress/strain fields and slab separation from the base.
