Combination Rules

Dynamic wind loads on tall buildings can be decomposed into three components, i.e. two translational components and one torsional component. When one component reaches its maximum, the other two components have low probability to take their maximum values. It is common to use combination coefficients for estimating the mean extremes of linearly combined wind loads. The traditional design practice for determining wind load combinations relies partly on some approximate combination rules and lacks a systematic and reliable method. Based on the high frequency force balance (HFFB) testing results, wind loads can be acquired in terms of time history data, which provides necessary information for the more rigorous determination of combination coefficients by probabilistic methods. In this paper, a 3D copula-based approach is proposed for determining the combination coefficients for three stochastic wind loads associated with a specific exceedance probability and a set of 3D realizable equivalent static wind loads (ESWLs) on tall buildings. Using the measured base moment and torque data by the HFFB wind tunnel test, a case study is presented to illustrate the effectiveness of the proposed framework to determine the dynamic wind load combinations and associated 3D realizable ESWLs on a full-scale 60-story building.

Abstract: The requirement of tall building in recent years increase the construction to satisfy the need of human beings. Very tall buildings located in high velocity wind area are highly sensitive therefore calculation and analysis of wind load is very impotent. Due to change in climatic condition the basic wind speed are increases. The main aim of this paper is to introducing the different techniques which is used to reduce the effect of wind load or lateral loads.

Wind Analysis

Now every day, various buildings are being built for different purposes such as residential, commercial, and industrial etc. In general, in order to stabilize these longitudinal tall structures for both loads such as gravity and lateral (wind and earthquake) loads are required to take when considering the analysis and design. In addition to this there are several types of structures or buildings having different geometry in vertical and horizontal plan in the sense regular or irregular. This paper presents detailed review on the analysis of vertically irregular structure subjected to wind loads, the failure of structure starts from the weak point or joint. This weakness is exacerbated by the uneven distribution of mass, changes in elasticity or stiffness and also changes in the vertical geometry of the structure. Properties that have objections to physical or geometric regularity are referred to as irregular structures. The present study shows a review on analysis and effects in vertical irregular structure under lateral load especially in case of wind load. Many structural software and standard codes are reviewed for the creation of all members under wind load. At the end of this paper concerns the comparison of regular building with irregular structure and describes the effects in vertical irregular structure with the help of structural behaviour such as displacement, drift, axial forces, base shear and bending moment etc.

Lateral Deflections

The design of lateral load resisting elements of tall buildings in regions of low to moderate seismicity is normally governed by the requirements to meet inter-storey drift limit under wind load. The key objective of the design of tall buildings is to provide adequate lateral stiffness to the buildings to limit their lateral deflections and inter-storey drifts under the lateral load. The current design practice assumes that only the structural skeleton provides lateral resistance against wind load. Although the effects of nonstructural elements on the lateral stiffness are widely acknowledged, the effects are often ignored in the analysis of the buildings. This paper presents a state-of-the-art of review on the effects of nonstructural elements on the lateral deflections and inter-storey drifts of buildings at serviceability limit states. It was found that ignoring the nonstructural elements could significantly underestimate the lateral deflection for certain types of buildings. However, the shape and form of the lateral deflection in the overall building is not significantly affected by the nonstructural elements.
