Research on mechanical property of SFRC was done through experiments of two SFRC T-beams and one concrete T-beam, while the influences of different volume fractions of steel fibers on integral rigidity, ultimate shear capacity, and the crack distribution characteristics were analyzed. ANSYS finite element software was used to simulate the tests and it was found that there was good conformation between the results of ANSYS simulation and tests. The test results and finite element software simulation both showed that the incorporation of steel fibers in the concrete can increase the integral rigidity and ultimate shear capacity, while partially reducing the propagation of cracks effectively. It was also proved that it is reliable to simulate SFRC T-beam by ANSYS software.

Through the finite element software, the stress and plastic strain of steel plate and concrete in different loading stages of the wall are analyzed, the mechanical properties and failure rules of the wall are revealed, and the failure mechanism of the wall is obtained. The comparison with the test results verifies the correctness of the finite element analysis. Through nonlinear finite element parameterization analysis, the composition of shear capacity of each composite wall is obtained. Based on the superposition theory, practical calculation formula of its shear capacity is given, and through a comparative analysis with simulation test results, the goodness-of-fit is satisfying.

Because of the low height of the prestressed short rib T-beam bridge and the poor torsion resistance of the main beam, the positive moment in the middle span of the bridge deck will increase correspondingly compared with the normal rib beam bridge. At present, there is little research on the calculation method of the bridge deck of the prestressed short rib T-beam bridge. In this paper, the space finite element method and the continuous one-way slab method are used to calculate the forces on the bridge deck, based on the space finite element method, a finite element elastic supported continuous beam method is proposed to calculate the forces on the bridge deck. By comparing the calculation results of the three methods with the test results, the reasonable calculation method of the bridge deck is studied. The results show that the spatial finite element analysis method can simulate the mechanical performance of the deck of the bridge of the prestressed short rib T-beam bridge well, the stress calculation results are consistent with the test results, and the calculation accuracy is high, which can be used in the actual engineering design; The finite element analysis method of elastic support continuous beam can also simulate the mechanical performance of the deck of the bridge of the prestressed short rib T-beam bridge. The concept of the method is clear, the calculation is convenient, and it is more suitable for the application of engineering design; The calculation results of the continuous one-way slab method are too large to be safe for design.

The experimental and analytical behavior of 400 kV S/C portal-type guyed towers under different loading conditions is presented. The portal-type tower essentially consists of two masts extending outward in the transverse direction from the beam level to the ground. In addition, two sets of guys connected at the ground level project outward along the longitudinal axes and converge in the transverse axes. The experimental behavior of the guyed tower is compared with the results of finite element analysis. The 400 kV portal-type guyed towers with III and IVI type insulator strings are analyzed using finite element software. Full scale tower test results are verified through comparison with the results of the finite element analysis. The initial prestress in the guys is allowed to vary from 5% to 15% in the finite element modeling. The effect of prestress variation of the guys on the tower behavior is also studied.

The rule of stiffness and deflection change of reinforced concrete two-way slabs strengthened by CFRP was discussed after test research. The results were analyzed with ANSYS finite element software and compared with test results, and the ANSYS finite element analysis results agreed well with test results. It shows that CFRP can improve the flexural stiffness of reinforced concrete two-way slabs and effectively restrain deflection deformation of them. So ANSYS analysis results can provide reference for the test and engineering.

18 different groups of hybrid fiber (steel fiber and polypropylene fiber) reinforced HPC deep beams and 2 groups of HPC deep beams without fiber were made. The shear tests under the static load and the numerical simulation by ABAQUS were conducted. Good agreement are found between test results and simulation results.The results of finite element analysis indicate that with the increment of reinforcement ratio, the shear capacity of hybrid fiber reinforced HPC deep beams increases, but quite limited. The variation of shear capacity of hybrid fiber reinforced HPC deep beams is not obvious as the shear-span ratio changes (when ) . The increment of span-depth ratio can improve the shear capacity of hybrid fiber reinforced HPC deep beams, but only with small amplitude. All these regularities are similar to those of ordinary reinforced concrete deep beams.

Considering two-way fluid-structure interaction and using finite element software ANSYS simulation study of cylindrical pier at different flow rates caused by the interaction of the river and pier piers vibration problems, through the discrete solution of wet modal method, and combined with engineering example, the analysis results using Lanczos method extraction, introduction of green's function of point source, using the finite element-boundary element analysis wet modal and wet frequency of the structure. Numerical results show that: Frequencies of wet modal than no fluid medium under the influence of modal frequencies is much lower. So for underwater structures, when analysis the modal,it is must be considered the fluid influence of wet modal.

The application of ABAQUS finite element software non-linear finite element analysis of brick masonry walls with structural column. Build three brick masonry wall models, and analysis of the damage form of the wall under different vertical compressive stress and horizontal force. Thus the analysis result compared with the calculation result of the relevant specification formula, in order to get validate compression influence of masonry aseismic walls. It turned out that different vertical compressive stress effect the shear capacity, and failure mode of brick masonry wall structure with a structural column.

The most commonly and popular type of bridge used in Nepal is T beam bridge due to it's simple in design, construction and maintenance than other types. T-beam Bridge comprises of a concrete slab integral with girders. This type of bridges is more preferred when it comes to connectivity to short distances. So, it is necessary to update the analysis and design methods. Here, in this paper, there is an attempt to study the comparison of maximum bending moment due to live load in a girder and slab bridge for varying span length as 15m, 20m and 25m respectively of T Beam bridge using conventional method. The same bridge is analyzed as a three-dimensional model in finite element software as SAP2000, apply the same loading done for conventional methods and compared the results. The maximum bending moment results obtained from finite element model are lesser than Courbon's method which looks more conservative.

Based on ABAQUS general finite element software, UMAT Fortran subroutine is compiled to estimate the long-term deflections of prestressed concrete beams. And the calculated values using the software corresponded well with the laboratory results. By generalizing key parameters impact on long−term deflections of prestressed concrete beams, time-dependent finite element analysis was conducted. Taking type of concrete, concrete grade, age of concrete when the initial stress was applied, effective prestressing tensile force, type of prestressed tendon, reinforcement ratio for nonprestressed compression steel reinforcement and mean relative humidity into account, a simplified formula for long-term deflection of prestressed concrete beam at midspan was suggested. And the calculated values using the suggested formula corresponded well with the laboratory and filed test results. The errors were within 10%. However, the calculated errors using the common codes were larger, which resulted in the unsafe values.
