Abstract: In this paper, we present the results of a program of static and cyclic triaxial tests, isotropically consolidated and drained or not drained, intending to characterize the mechanical parameters of some typical alluvial gravels of the San Juan River. We determined the pre-seismic mechanical properties of these gravels: the hyperbolic curve stress-strain; the variation of the shear resistance in function of the confining pressure; the variation of the Young modulus with the initial confininig pressure; Young modulus with load-unload; the volumetric variation and variation of the B modulus with the confining pressure. In order to carry out this triaxial tests, the following effective pressure values were used in the cell: 1.0 , 2.5 , 5.0 and 9.0 kg /cm2, in the case of the drained and of 1.0 , 2.5 , 5.0 and 8.0 kg/cm2, for not drained. Samples were molded to different relative densities of interest. The cyclic triaxial tests allowed us to determinate the dynamic properties of the aboveme

Abstract: This paper presents the behavior and the modes of failure of cold-formed steel wall plate system subjected to different load position. An experimental investigation was conducted on a full scale wall plate system. Load was applied at the mid span of the wall plate and the system was tested to failure. The behavior of the system was observed and the data collected was used to calibrate a numerical model for parametric study. To study the effect of load position on the system, a concentrate force was applied at different positions on the wall plate. Different failure modes and capacities were observed as the load moved away from the mid span of the wall plate. The system had the highest capacity when load was applied at the support and the lowest ultimate capacity when load was applied at the mid span of the wall plate
