Analysis of laterally loaded piles with rectangular cross sections embedded in layered soil

Abstract: An analysis is developed to determine the response of laterally loaded rectangular piles in layered elastic media. The differential equations governing the displacements of the pile–soil system are derived using variational principles. Closed-form solutions of pile deflection, the slope of the deflected curve, the bending moment and the shear force profiles can be obtained by this method for the entire pile length. The input parameters needed for the analysis are the pile geometry and the elastic constants of the soil and pile. The new analysis allows insights into the lateral load response of square, rectangular and circular piles and how they compare. Copyright © 2007 John Wiley & Sons, Ltd.

Nonlinear Modeling and Analysis of R.C. Framed Buildings Located in a Near-Fault Area

Abstract: Structural damage to r.c. buildings located in a near-fault area has been observed during strong ground motions, with long-duration horizontal pulses and high values of the ratio between the peak value of the vertical acceleration and the analogous value of the horizontal acceleration. The design provisions of current seismic codes are generally not very accurate for assessing the structural effects of near-fault ground motions. In the present work, six- and twelve-storey r.c. spatial frames are designed according to the provisions of the Italian seismic code, considering horizontal and vertical seismic loads in a high-risk seismic region and assuming low and high ductility classes. A lumped plasticity model based on the Haar-Karman principle is used to describe the inelastic behavior of the r.c. frame members. In particular, the lumped plasticity model for a column includes a piecewise linearization of the bounding surface of the axial load-biaxial bending moment elastic domain, at the end sections where inelastic deformations are expected. Moreover, the lumped plasticity model for a girder takes into account the potential plastic hinges along the span, due to the vertical ground mo- tion, so avoiding the computational effort required by the sub-discretization of the frame member. The nonlinear dynamic response of the test structures is studied with reference to the horizontal and vertical components of near-fault records. The occurrence of a directivity effect at arbitrary orientations is checked rotating the horizontal components of the se- lected motions, rather than considering only fault-normal and fault-parallel orientations.

Elasto-plastic stress analysis in an adhesively bonded single-lap joint

Abstract: In this study, an analytical elasto-plastic stress analysis was proposed to determine the shear stress in a ductile adhesively bonded single-lap joint. DP460 adhesive was employed in the present study. The von-Mises criterion was used for checking the yield condition of the adhesive material. In the solution, the shear stress was assumed to be constant across the thickness of the adhesive. Bending moment was neglected in the solution. Analytical results were checked by using the finite element analysis. ANSYS 10 was employed in the numerical solution. Analytical and numerical solutions are found to be in a good agreement.
