“…During the experiment, a hydraulic jack on the column imposes a fixed axial load on the column which is indicative of the gravity load obtained from the frame analysis [35]. In this set of experiments on the compressive strength of concrete, all samples were selected in the range of 21.45-19.78 MPa.…”

A finite element method was used in this study to investigate the effects of openings on the resistive behavior of concrete slabs. The presented modeling procedure is used to conduct numerical analyses on the response of reinforced concrete slab subjected to in-plane monotonic loads in X (perpendicular to the beam) and Z (parallel to the beam) directions. Initially, the developed numerical model was calibrated and compared with laboratory results. In building this three-dimensional model, it is attempted to accurately model all nonlinear properties of steel and concrete materials as well as the interactions between them. Then, the behavior of bilaterally concrete slabs under different loads was investigated and used as a reference. Finally, the effect of openings under different loads on the strength of concrete slabs was studied. The results confirm that openings have a great influence on the change of hardness, ductility, initiation and cracking path, and stress distribution under shear and gravitational loading. Moreover, by adding an opening inside the diaphragm, not only did beam and block flooring show more fragile behavior, but also its strength and resistance decreased against lateral load. Given the results of the parametric study of the effect of layout, generally, its place became critical at the state that opening disturbed transmission of shear stresses to the collector beams. By adding the area of the opening and loading in X direction, the concentration of the tensile stresses (equivalent to main maximum stresses) was at the tensile edge as well as at the middle of the flooring around the opening. It is worth noting that an increase in the opening’s area caused the number of tensile stresses to be increased at the middle of the flooring. Meanwhile, the concentration of maximum compressive stresses which is equivalent to the main minimum stresses was at the compressive edge, started at the area of the collectors, and stretched to the edge of the opening. Among different layouts, X-1 and Z-3 states were more critical than other states. Considering openings with different layouts, X-1 and Z-3 have the most stiffness deteriorating and strength in such a way that stiffness deteriorating and strength were 39.93% and 37.89%, respectively, for Z-3 model and 38.68% and 43.33%, respectively, for Z-3 model.

The bridge approach road embankment has a very important role as a link between the road and the bridge. In the post-construction stage, there are many cases of bridge approach road embankments, especially those with high elevations, potentially experiencing differential settlement. To overcome this, an analysis and planning study was carried out in increasing stability and overcoming the differential decline that occurred in the bridge approach road structure, especially in the approach slab structure with the end of the bridge. So that a bridge approach road model was developed as a substitute for the mass of soil embankment by conducting experiments and making a prototype of the Precast Concrete-cell Box structure model, which was given the maximum repetition and gradual plan load. While the method used in this research is the prototype model method, by conducting loading and settlement experiments on the bridge approach, especially on the approach slab. Furthermore, analysis and simulation are carried out under the condition of reaction force and maximum loading. From the results of the analysis, in the loading test of 2,761.00 kg, 2,717.00 kg 2,974.00 kg on the prototype model, the value of the decrease in LVDT 1-2-3 was 0.00 mm, the loading test of 3,956.00 kg and 3,887.00 kg obtained the value of the decrease in LVDT 1 and LVDT 3 of 0.00 mm and LVDT 2 obtained a decrease value of -0.01 mm which indicates a bending / deflection occurs in the approach slab structure, but it is still safe and no structure is required..

The culverts are used to safely convey water under railways, highways, and overpasses. They are utilized in drainage areas or water channels and in areas where the bearing capacity of soil is low. The design and construction of this crucial infrastructure need to be improved to meet contemporary demands of reliability and affordability. Precast reinforced box culverts are popular alternatives as they ensure strength, durability, rigidity, and economy. This research seeks to develop an effective and affordable design improvement procedure for a precast box culvert using modern numerical tools. The Finite Element Method (FEM) based approach is used in studying the effects of haunch geometry and additional steel reinforcement on the load-bearing capacity of box culverts. A conventional box culvert is analyzed to create the numerical models in the Abaqus FEM code and to investigate the load-bearing capacity of culverts with an expanded span. The outcomes of the study reveal the critical places for stress concentration as well as the location of maximum damage. It is found that haunch geometry and additional reinforcement at these critical places significantly affect the load-carrying capacity of a culvert. From the comparison of capacity curves of models with and without haunches and diagonal reinforcement, it is found that a 25% increase in load-carrying capacity is achievable with the recommended changes. The proposed design improvement technique can be employed for the cost-effective and safe design of a concrete box culvert with larger span lengths and high water-flowing capacities. The findings of this study are expected to assist practitioners in strength enhancement tasks of box culverts for increased structural stability and drainage efficiency.
