Typhoon’s damage to curtain wall

Typhoon is one of the natural disasters encountered in China’s coastal areas all the year round. It causes incalculable economic loss and harm to life in China every year. With the increase of super high rise buildings in coastal areas of China, the influence and damage of typhoons on door and glass curtain wall in coastal areas, including metal roofing, are very significant in recent years. Large area of glass damage is the most common damage caused by strong typhoon to building Windows and curtain walls, and some are even very serious. The opening parts of the curtain wall and doors and Windows are the parts with weak wind bearing capacity. The opening fans fall off and fall because of lax locking or insufficient wind bearing capacity during typhoon. Although the overall collapse of doors and Windows is not common, but for the existence of design and installation defects of the doors and Windows, under the action of a strong typhoon, the overall collapse is inevitable and inevitable.

After experiencing the destruction of typhoons in recent years, people’s safety awareness of door and window curtain wall has been further improved. For the impact and damage caused by typhoon to us, the problems existing in the engineering design and construction of building doors and Windows curtain wall need us to seriously face and think about, and take effective methods to deal with. Windows and doors curtain wall are serious damaged in recent years, the basic level 14 or more powerful typhoon, some people think that in order to ensure the safety of the curtain wall structure under the action of a powerful typhoon, the wind resistance design of Windows and doors curtain wall, should improve the level of building Windows, the current design specification of wind load value whether it is feasible to be confusion. In the design scheme of door and window curtain wall project, some construction units put forward that the wind resistance design of door and window curtain wall should ensure that no damage can occur under the action of any typhoon. In order to take care of the safety and the optimization of construction cost, some even adopt two wind load value methods for the walls in different directions of the same project.

Through to the coastal areas in recent years to strong impact on the building Windows and doors curtain wall limited analysis as you can see, in strict accordance with the current standard specifications for the design and construction supervision of building Windows and doors curtain wall, in the role of resistance to strong has the ability of reliable enough, most of the structure of hidden frame glass curtain wall are stable. For the strong typhoon window curtain wall, including some damage of metal roof, we should be scientific analysis and face.
