Abstract: The paper presents experimental shear tests of 18 beams tested with three main variables; the reinforcement ratio, the shear span to depth ratio, and the total depth of the beam. The paper introduces a novel approach in utilizing the knowledge about shear resistance degradation by coupling the shear resistance with the shear demand. Both the shear resistance and shear demand are correlated with flexural tensile strain from compatibility and equilibrium requirements. The basic shear strength, under a given loading is determined from the intersection of the demand and resistance curves. The procedure was verified against the results of the tested beams. It showed good prediction capability and can be useful to design practice.

Abstract: Almost all types of piles are subjected to lateral loads. In many cases, however, the applied lateral loads are comparable with gravity loads. Lateral loads and moments are generally induced from wind and earthquake. All piles which are subject to lateral loads are usually divided into two categories: long piles and short piles. The general methods to estimate lateral bearing capacity of piles are based on ultimate bearing capacity and allowable horizontal displacement for short and long piles respectively. Several theoretical methods including Hansen, Broms, Petrasovits, Meyerhof, Prasad and Chari have been proposed to predict lateral bearing capacity of piles in cohesion-less soils. All these theories are based on simplified soil pressure distribution assumption along the pile length. In practice the Broms method is most popular, since it is simple and applicable for both of short and long piles. In the present research steel pipes are used as pile in laboratory to evaluate lateral c
