Geometry of the Pile-Cap. Try an overall depth, h=1000mm, effective depth =900mm. Spacing between pile = 3×400 = 1200mm. Overhangs from edge of piles = 150mm. Length of pile = 1200+400/2+400/2+150+150 =1900mm. Width of pile cap = 400+150+150 = 700mm.
Design the pile cap shown in the following figure with 12 in. diameter piles and a service load capacity of 50 tons each. The pile cap has normal-weight concrete with a compressive strength of 4000 psi and Grade 60 reinforcement.
In this example the reinforcement of a pile cap is determined using strut-and-tie models (NEN-EN 1992-1-1, 6.5). The strut-and-tie model for a pile cap supported by two piles is depicted in Figure3.
17 lut 2020 · Structural design of pile foundation and design of pile caps based on practical design experience, and their interaction with ground beams and slabs.
Pile caps are constructed to hold the pile and superstructure together at the ground level or below the ground level while transferring loads of the superstructure to the foundation. Generally, pile caps are constructed to connect one pile, two piles, three piles, four piles or a group of files.
3 kwi 2018 · Pile caps are concrete mats that rests on piles with adequate rigidity to transfer the column loads to the piles. Piles are provided as alternatives to shallow foundations when a firm and stable soil to carry column load is too deep below the surface, or when high lateral load is anticipated.
2 kwi 2021 · Pile cap design involves analyzing the superstructure load path and determine the magnitude of force the pile cap undertakes. The pile cap is then designed and checked against large moments, shear and punching shear around the piles.
