Numerical calculation of evaluating equivalent static wind loads on long span roof structures;

The methods to obtain the background component of structural equivalent static wind loads systemically are discussed.

Comparing with conventional method,the recommended approach,not requiring getting equivalent static wind loads(ESWLs),is reasonable,simple and of value to be popularized.

Study in time domain on equivalent static wind load of large span steel structure;

Based on the modified SRSS method,an equation for equivalent static wind loads combining mean,background and resonant components,is derived.

It is important to determine the wind-induced response accurately and formulate the component of equivalent static wind loads of large span roofs reasonably.

The research of the equivalent static wind load on tall buildings;

,load-response correlation(LRC) and quasi-mean load(QML) and gust load envelope(GLE)methods are verified in terms of their accuracy in describing the background equivalent static wind load distribution on high-rise(buildings.

The equivalent static wind loads (ESWL) provide an effective approach to deal with the spatiotemporally varying wind loads for structures with long span roofs.

The equivalent static wind loads (ESWL) which produce maximum peak responses of roof-structures are formulated based on the modal expansion of the resilience and the quasi-static equation for calculating responses.
