Static pile load test to failure is the ultimate procedure available to examine the capacity and integrity of deep foundations. Being expensive and time consuming, the procedure is often substituted for the application of a load to a certain factor (most often two) times the contemplated design load. In fact, only a proof test is carried out while the ultimate capacity and actual factors of saf...

For the optimum design of Piled Raft Foundations (PRF), the concept of settlement reducer piles has been applied. However, when these piles are connected to the raft, a high stress may develop in the relatively small number of piles. Therefore, an alternative approach is to disconnect the piles from the raft forming a new system called a non-connected or disconnected piled-raft foundation (NCPR...

Due to its faster implementation and potential cost savings for estimating the bearing capacity of PHC pipe piles, High Strain Dynamic Test (HSDT) offers an alternative approach Static Load (SLT). The report presents a study via those methods with sliding micrometer. And Pile Driving Analyzer (PDA) imported from United States is employed, determine design parameters pile foundation engineering ...

Abstract. Contemporary civil constructions are based on foundation systems consisting mainly of shallow, semi deep and foundations. The screw pile resembles essentially to a large that is inserted into the ground by special machine. Basically, it acts as or an anchor. In general, composed central shaft one more graded steel helices. Screw piles have made great progress in recent decades, partic...

Pretensioned spun high-strength concrete (PHC) piles have been widely used in the pile foundations of buildings soft soil areas due to their high axial bearing capacity and good economic benefit. However, behavior PHC under lateral loading is generally poor this restricts application high-intensity seismic regions, especially for high-rise buildings. The existing research on performance cyclic ...

Several deficient steel structural members require to be strengthened all over the world. In this article, horizontal defects were generated at three locations (top, middle, and bottom) on the middle element and the middle of the side element. Consequently, the effects of the location of such defects on axial behavior of Carbon Fiber Reinforced Polymer (CFRP) strengthened steel Square Hollow Se...
