Behavior of column-foundation joint under vehicle impact. International Journal of Impact Engineering, Vol. Structural Concrete. Materials with complex behaviour, pp. Page Count Abstract The basic principle of the concrete mechanics project, is to analyze structural behavior of reinforced concrete members by adding up effects from cracking, bond-slip behavior and aggregate interlock into a numerical scheme which accounts for the geometry of the structure under consideration.
This indicates that ton cargo trucks the maximum truck loading in South Korea might cause bridge collapse. However, displacements among the three different models with the Type II column were similar because there was no shear failure, only local spalling. This should however still be verified with experimental data prior to implementation. The test and simulation results show that the effect prestress obtained from indirect measure methods can reflect the prestress history relatively well. Figure 9.
The question then arises as to which stiffness states to consider. As discussed in Section 2 the E-modulus of the material can be changed to give an equivalent bending stiffness to the plate formulation. Analysis of recent bridge failures in the United States. For the Type II column, all models showed similar failure deformation, since only local concrete crushing failure occurred. The overall solution is a nonlinear analysis, but the intermediate solution procedure is in essence a repetitive linear static solution updating the stiffness matrix after each converged load step. Following the saving of the incremental results, the new modified E-modulus must be assigned for each of the Gauss points within convergence limits or equal to strain limits as dictated by the input stress-strain graph.

The final experimental test case is that of a two-way spanning slab, specimen C1, tested by Ghomein and MacGregor . Experimental Cases To evaluate the appropriateness of the proposed method, three experimental test cases were evaluated. Analysis of ultimate states of reinforced concrete wall-frame structures.
Modelling and Computational cost The time required for modelling a reinforced concrete structure for non linear analysis are noticeably higher compared to the required by the traditional linear analysis. Google Scholar  Swertz S.
In the experiment a one-way spanning slab was subjected to an increasing edge moment loading in one direction only, Figure 7 a.
Since a large amount of impact energy was used to initiate the movement of the mass element, the final displacement decreased compared to Model II. The displacement components of co-ordinates x, y and z obtained from the plate element based on small displacement theory are given by equation 5.

book two as approaches was based on flexibility and rigidity. This decision would depend on the fineness of the discretisation which should be able to sufficiently represent the distribution of yielding throughout the slab.
Figure 2. During the experiment cracking was reported at an applied moment of 75 kN. In the first approach, nonlinear springs based on moment-rotation and force-displacement curves are used and nonlinear volume is assumed to be lumped in the specific location of the element.
Meanwhile, the indirect measure method has the advantages of low cost and easy operation, which can be exploited and developed in general projects so as to get the stress history of the prestressed reinforcement in time and reduce potential security threat.
For this procedure the convergence criteria is defined by equation 15 as given by Roberts . A and Vecchio, F. Slab C1 was modelled as simply supported along the sides of non-symmetry. When reviewing the first analysis, loading continued to increase and analytical slab yielding was seen and eventual ultimate yield line loading identified as The ton trucks had the heaviest cargo, which led to the largest second impacts on the target.
By using this method accurate moment redistribution results can be established.
