工程结构的风灾破坏和抗风设计

风是自然界常见的一种自然现象 ,国内外每年都会发生因风灾而造成的严重灾害。风灾损失的主要形式之一是工程结构的损坏和倒塌。因此 ,工程抗风设计计算的合理和全面与否是工程安全的重要关键 ,抗风设计也是工程结构中的重要研究课题。笔者结合我国的有关抗风工程的工程规范 ,介绍了风对结构的作用、工程结构的风灾破坏形式和抗风设计的主要研究内容。最后 ,笔者对抗风工程的研究进行了展望。

Disaster Caused by Wind and Wind-Resistant Design of Engineering Structure

Wind is a natural phenomenon, which can cause great disaster every year all over the word. Rational and all side design computation of the wind resistance is the key factor in safety engineering, which is also an important research project in structure engineering. According to the wind engineering codes in China, the author introduces the interaction between the wind and the structure, the destruction modes of the structure, and main research contents of the wind engineering. Finally, the research of wind engineering is prospected.
