Load Factors for Dynamically Sensitive Structures wind load factors for dynamically sensitive structures

Published 2009. The current recommendations for load factors concerning wind are based on rigid buildings, which may not be adequate for dynamically sensitive structures. In light of the uncertainties associated with the dynamic characteristics of buildings (e.g., mass, stiffness and damping), the departure of response being proportional to the square of wind velocity, and the (plate) How are wind loads induced at various heights?How are wind loads induced at various heights?The wind loads induced at various heights, base shear and base moments for the building has been computed by Peak Wind Approach as well as Mean wind Approach associated with Gust Factor.

Dynamic Approach to the Wind Loading of Structures wind load factors for dynamically sensitive structures

Abstract. This paper provides a general framework of the dynamic approach to the wind loading of structures, in particular of vertical structures such as buildings, towers and chimneys. The first part of the paper deals with the classical problems of the dynamic alongwind response and of the equivalent static forces, defining a chain of nondimensional coefficients, referred to as the gust (plate) Dynamic assessment of wind sensitive stadium structures(steel) Wind loads on structures are affected by both the mean wind speed and turbulence. Note that Wind Engineering is normally associated with a neutrally stratified boundary layer, and that for high wind speeds it has been found that there is little deviation from neutral boundary layer properties (Simiu & Scanlan 1996).(plate) Estimated Reading Time 4 minsGUST FACTOR METHOD FOR WIND LOADS ON (steel) For designing wind sensitive structures, proper assessment of wind loads is necessary. In the evolution of structural design for wind loads, methods have vastly improved during the last few decades from simple static wind load to quasi-static approach and then on to refined dynamic wind load for more wind sensitive structures.

FACTORS AFFECTING WIND LOADING Wind loading is dependent on several factors relating to the location of the site and the geometry and orientation of the building. For this reason, wind loading is site and building specific, so must be calculated for each individual building. The main factors that influence wind speed are Location Altitude(plate) LOAD AND RESISTANCE FACTOR DESIGN (LRFD) (steel) load categories modified by relevant load factor s. Load factors can be greater than, less than, or equal to 1.0. The effects of the factored loads are the responses of the structure subjected to the factored loads. The structural responses are typically expressed in the form of, for instance, internal forces, internal moments,
