Modeling of single pile behavior is examined using AXIS 8 VM and PLAXIS 3D software packages, and the database of 20 pile load tests made in Hungary. Cone Penetration Test diagrams and the load-displacement curves are used to determine the soil mechanical parameters and the limits of pile resistances as input data for the numerical calculations. The goal of this work is to assess how precisely can be determined the load-settlement curve using available interface and sub-grade reaction models compared to the field load test results. This study is the first stage of improving the combined pile-raft foundation modeling.
This paper describes wood-concrete structural members in which the interlayer connection is achieved with adhesives, by overlaying the fresh concrete over the top of a wood layer to which moisture tolerant adhesive coating was applied a short time before the casting. Laminated wood-concrete structural members could be built as beams or slabs. Experimental results presented on eight laminated wood-concrete beam specimens subject to static loading indicate that the load capacity of the laminated wood-concrete beams exceed the performance of the classical wood-concrete beams which use shear notches cut into the wood for the interlayer connection.

In a wood-concrete composite structural member the wood layer overlapped by the concrete layer are interconnected to prevent the relative slip. In this research notched shear-key interlayer connections were used. A problem with using these novel composite members in bridges is that the fatigue behavior of the composite member is not well known. This paper presents an S-N curve for fatigue verification of notched wood-concrete connections based on static and low-to-high-cycle repeated loading tests on fourteen composite beam specimens. The points on the S-N curve were determined for three levels of the maximum load as a function of the average static failure load.
The paper presents results of the analysis of the lateral-load response of an existing RC structure seismically
upgraded by means of C-FRP. The structure was tested “as-is” under monotonic lateral loading conditions. It
failed by a column-type collapse
mechanism. The structure was repaired and upgraded by means of C-FRP. The
structure has been tested again by a cyclic load test. Results demonstrate the
successful implementation of C-FRP with a significant improvement of stiffness,
strength and lateral displacement capacity of the upgraded structure. Finally a
numerical study has been started with the aim to correctly capture the
