The relevance of the study is associated with the need to determine scientifically based principles for the design of wind-powered high-rise buildings. The article analyzes the main climatic parameters affecting the design of wind-powered high-rise buildings. While current research focuses mainly on the technical performance and savings of wind power plants (WPPs), modeling wind energy potential based on the analysis of climatic parameters allows you to optimize design solutions taking into account the influence of the environment. For various stages of the design of the integration of wind turbines into a high-rise building, it is important to take into account the dimensions of climate systems (macro, meso and micro levels), based on the laws operating within certain territorial boundaries. The article discusses the macroclimatic indicators that determine the total energy resource of wind in the region. The influence of the parameters of the mesoclimate on the wind potential has been determined, in accordance with the characteristics of the natural and anthropogenic environment (relief, the presence of forests, proximity to water bodies, urban development). The parameters that clarify the energy potential of the wind at the microclimatic level, taking into account the location of the wind turbine in the building, have been investigated. As a result of the analysis, a diagram of the structure of preliminary modeling of the energy wind potential at various climatic levels in the design of wind turbines in high-rise buildings has been determined.

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.

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.
