Abstract High-rise pile cap foundations are generally used to support offshore wind turbines or sea-crossing bridges. They endure complex wave loads due to the interaction of free surface and the cap. An additional pressure increment has been found under the cap when free surface impinges the cap bottom. This additional pressure changes the wave loads on the piles under the cap compared with the case without the cap. In the present paper, we investigate the effects of the cap bottom elevation on the wave loads of the piles under the cap by using fully nonlinear numerical simulations. Based on parameters of waves and the structure used in Donghai Bridge Wind Farm, China, we simulate a number of cases with different cap bottom elevation to explore its influence on wave loads of the piles under the cap. We find that the influence is of significance and requires enough attention.

<p><em>Pile foundation is one of the solutions of high-rise buildings not in the area of restrict area. When the pile foundation reached until the hard ground reaches, a small settlement is expected and  different  setlement  are  not occur. The objective: analyze the results of loading tests compared carryng capacity calculations, pile cap thick required secure.</em></p><p><em>The research method used in this research is the case study of pile foundation  twelve floors building in Batam island. The reaction on the pile is analyzed using software program of non-linear structure version 9.5 which is supported by primary data, namely loading test and secondary data of soil investigation and the largest column force taken on the pole 1.618,854 ton, Mx -7,936 ton meter, My -75,531 ton meter.</em></p><p><em>Carrying capacity analysis is based on friction and end bearing and calculated pole efficiency. The axial load of the plan is supported by 16 (sixteen) piles, based on the loading test (P) the ultimate pile foundation reaches 200% (two hundred percent) in the amount of 411.52 tons. </em><em>Single pile carrying capacity is 205.76 tons .Settlement in the loading test results 10mm is smaller than from the setlement in calculation results. The stress acting on the pile cap of 12.453 kg/cm<sup>2</sup> is smaller than the permit strees of 13 kg/cm<sup>2</sup>.</em></p>

Construction of pile foundations is also called a foundation in construction enabled to heavy loads (high rise building). Before the implementation of the construction of the first construction is implemented and carried out in the field is the work of the foundation (bottom structure). Foundation work itself is very important for civil engineering works, because this is the foundation that secures simultaneously carry the load working on the construction. This study aimed to analyze the carrying capacity and the forces acting on the pile working from the Standard Penetration Test (SPT), the data kalendering pile installation time, then the data terbebut in include into the application to determine how far the resilience of construction are already working. Methodology The data collection is done by making observations, collecting data from the project and conduct a literature study. From the analysis of the structure obtained by the forces at work in the use of the calculation of the structure. The calculations show that the pile cap and slab reinforcement in accordance with the moment that occurs, the strength and bearing capacity of the pile meet safety requirements.

This paper introduced the reconstruction practice and detailing of a high-rise reinforced concrete frame-shear wall structure. To fully utilize the old structure and meet the requirement of the reconstructed structure, certain measures have been put forward. The enlarging of concrete pile cap and adding strip foundation-beam were used to support the new added shear wall. The reconstruction concept detailing of the roof of basement, the enlarging of the beam or column sections and the application of the inclined column are introduced. The whole structure analysis shows that the reconstructed structure is safe enough to meet all the requirement of the designing code and the settlement observation shows that the deformation of the whole structure in gravity is small. The paper shows the design and detailing of the reconstructed engineering is effective and will be valuable to the similar engineering structures.
