Gust-front factor: A new framework for the analysis of wind load effects in gust-fronts
In comparison with atmospheric boundary-layer winds, which are customarily treated as stationary, gust-front winds such as a thunderstorm/downburst exhibit strong nonstationarity. In storms characterized by a gust-front, wind speed changes rapidly during a short time period. In order to realistically describe attendant loads effects, a new analysis framework is presented which is named the gust...

آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...
15 صفحه اولGust Loading Factor : New Model
Wind loads on structures under the buffeting action of wind gusts have traditionally been treated by the ‘‘gust loading factor’’ (GLF) method in most major codes and standards around the world. In this scheme, the equivalent static wind loading used for design is equal to the mean wind force multiplied by the GLF. Although the traditional GLF method ensures an accurate estimation of the displac...
متن کاملData Mining Methods to Generate Severe Wind Gust Models
Gaining knowledge on weather patterns, trends and the influence of their extremes on various crop production yields and quality continues to be a quest by scientists, agriculturists, and managers. Precise and timely information aids decision-making, which is widely accepted as intrinsically necessary for increased production and improved quality. Studies in this research domain, especially thos...
متن کاملDescription and Simulation of Gust Front Wind Field
An efficient model for simulating gust front wind field is proposed based on the time-frequency description of the wind field. Traditionally, transient or non-stationary random processes are simulated to account for amplitude modulations invoking envelop processes to shape these modulations. In this study, a time-frequency based scheme is introduced to account for both modulations in amplitude ...
