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

Abstract: Using bonded fiber reinforced polymer (FRP) laminates for strengthening and repair of structural members has been proven to be an effective and economic method. High strength and stiffness, light weight and good fatigue and durability properties of FRP composites together with advantages offered by adhesive bonding have made it a suitable alternative for traditional strengthening and repair techniques. It has also been recognized that pre-stressing the FRP laminates prior to bonding would bring additional advantages such as reduced crack widths, postponing the yielding in tensile reinforcement, increasing the load bearing capacity and saving reinforcement material. Using pre-stressed laminates, however, is associated with very high interfacial stresses in the bond line at the laminate ends, which necessitates the use of mechanical anchors. This paper presents a new method and a device for applying pre-stressed FRP laminates to flexural structural members without the need for mechanical
