2013年1月31日 · If your pile has tensile uplift load case, your pile head rebar definitely need to extend into pilecap. More than that, you have to check the pile head rebar anchorage length and ensure you have enough anchorage length as rebar development length ld (straight bar case ACI 318 12.2.1) or ldh (90 degree hook case ACI 318 12.5.1) to mobile the ...

2024年6月7日 · This paper focuses on the optimization of uplift piles for a base plate considering local anti-floating stability. According to the force characteristics of the base plate subjected to buoyancy, a bi-directional evolutionary structural optimization (BESO) process is proposed.

PROBLEM TO BE SOLVED: To provide a mounting structure of a base plate to a pile head, which absorbs horizontal displacement between a pile core and a superstructure, positively prevents...

minimize the deformation degree of the base plate by changing the distribution form of piles, including the pile length, pile diameter, and pile spacing. In summary, it is feasible to use the BESO method to study the optimization of uplift piles for the base plate considering local anti-floating stability. In the present work, a BESO

2024年10月17日 · Below is an example of some American Base Plate Calculations that are commonly used in base plate design. Often when designing base plates, we will consider a few different checks relating to the various components of a base plate, namely:

The utility model belongs to the field of buildings and relates to a pile for installing a base plate. The pile comprises a pile head, wherein the pile head is in a tube shape, an...

The through-hole 3a in the size larger than the size of the outer periphery of the pile head of the pile 1 is formed to the pile-head base plate 3. The base plate 3 is superposed on the subplate...

PROFIS Engineering models the baseplate using CBFEM – component based finite element method and a non-linear analysis. The components – profile, stiffeners, welds, plate, anchors and concrete – are modelled as below: Stiffness (k) of the anchor is built into the software and is activated by choosing a certain anchor.

Pile Caps as deep beams. When pile caps have the ratio of their length to depth to be greater than 2, they are designed as deep beams using truss analogy. The truss analogy assumes a concrete struct transfer the concentrated load from the column to the piles’ head, while the centers of the piles are connected by steel ties (steel reinforcement).

Base plates are usually used to distribute column loads over a large enough area of supporting concrete construction that the design bearing strength of the concrete is not exceeded.
