“…With the increase of complexity and lightness of structures, moderate nonlinearities in some specific structures need to be incorporated, otherwise, the GRFs that exclusively take into account linear effects will discount the safety of these structures (Kasperski, 1992, Kasperski and Niemann, 1992). At some positions of several cable-suspended and cable-supported membrane roofs-two sorts of typical nonlinear tensioning structures, Suzuki et al (1997), Shen and Yang (1999) and Zhou et al (2013) probed the GRFs of multiple kinds of control WISRs, and conceived some empirical and parametric equations or values relevant to weak geometrical nonlinearities manifested in Tables 2 and 3 and Figure 3, which broaden the GRF’s use scope.…”

Equivalent static wind load (ESWL) is helpful information for designing wind-sensitive structures since it converts complex wind-induced structural dynamic analysis into a simplified static analysis and facilitates combination of other loads or actions in structural designs. In recent years, there have been a growing number of long-span roof structures, most of which are sensitive to wind actions. Indeed, the accurate determination of ESWLs has been a primary concern in their wind-resistant design. Although some significant progress has been made on this topic, there are various issues to be addressed or improved due to a variety of reasons. With the further development of long-span roofs, there will be higher requirements for their ESWLs. This paper first combs through the existing representative methods depending on wind-induced structural responses (WISRs) and wind-induced structural stability (WISS), where the ESWLs linked with the former are the mainstream and the ones concerned with the latter are still somewhat in their initial stages of development. In each broad category, some momentous tactics of mathematics and mechanics are utilized to derive different methods. In the conclusion, this paper finally summarizes the existing achievements, highlights the technical challenges that hinder the current methods from being widely adopted and proposes some latent solutions for the future research. This review paper is anticipated to be a comprehensive reference for researchers and professionals in this field of study.

“…Due to simplicity, this method was adopted to study ESWLs on long-span roofs with different geometric and structural configurations (e.g. Lou et al, 2000;Shen and Yang, 1999;Suzuki et al, 1997;Uematsu et al, 1996Uematsu et al, , 2008Uematsu and Yamada, 2002). The load-response-correlation (LRC) method (Kasperski and Niemann, 1992) used the correlation coefficient between the loads and response to determine the ESWLs.…”

Long-span roof structures with multiple vibration modes may undergo coupled motions when exposed to spatiotemporally varying dynamic wind loads. This article presents a framework for the analysis of coupled wind-induced responses and equivalent static wind loads on long-span roof structures. This framework takes into account the intermodal coupling of modal response components and cross correlation between the background and resonance. The load-response-correlation method is widely used for the background equivalent static wind loads of rigid structures. Also, the concept of load-response-correlation was extended for the correct estimation of equivalent static wind loads by considering the correlation between the load and exact total responses. However, there is no detailed study for the correct estimation of equivalent static wind loads on the component of background, resonance, and their cross response using load-response-correlation method. In this article, a consistent load-response-correlation method for equivalent static wind loads is presented in a unified framework which contains the background, resonance, and modal coupling. First, the accuracy of wind-induced responses is ensured by considering the modal coupling. Meanwhile, the efficiency is improved by decomposing the covariance matrix of the generalized resuming forces. Second, several effects of the wind-induced responses are discussed in detail, such as the effect of the modal coupling, the effect of the modal participations to resonant responses, and the effect of the cross correlation between the background and resonance. Finally, the proposed equivalent static wind loads are represented by the composition of the external wind loads and inertial forces, which are both the most probable load distributions. Accordingly, the equivalent static wind load distribution and the responses by equivalent static wind loads are reasonable.

“…Starting from the available data on the pressure field measured on a model tested in wind tunnel, a multi-correlated field of the wind loading has been artificially generated to study the nonlinear response in time domain. Suzuki et al (1997) describes a large-span structure with a new structural system comprising a semi-rigid (flexible) hanging roof, and a response analysis taking into account geometrical non-linearity of the roof was carried out using ADINA (Automatic Dynamic Incremental Non-linear Analysis) to evaluate both static and dynamic response induced by static or fluctuating wind force. describes a simple method for evaluating the design wind loads for the structural frames of circular flat roofs with long spans, and the dynamic response of several roof models were numerically analyzed in time domain as well as in frequency domain by using wind pressure data obtained from a wind tunnel experiment.…”

This paper focuses on the wind-induced vibration response of prestressed double-layered spherical latticed shell (PDSLS) structures by adopting time-domain analysis method. Welch spectrum analysis method is used to make precision evaluation of power spectrum of fluctuating wind speed time history simulated by weighted amplitude wavelet superposition (WAWS) method and linear filtering method of auto-regression (AR) model. Results show that the two methods produce little precision difference, but AR method is far more efficient than WAWS and is more suitable for wind speed simulation of PDSLSs. The effect of various parameters on the wind-induced vibration response of PDSLS structures are comprehensively investigated, including rise-span ratio, span, shell thickness, elastic constraint stiffness, prestress value, with or without cables and cable layout scheme. Results show that rise-span ratio and span are the major factors that affect wind-induced vibration response of PDSLSs. When cables are set, the wind vibration coefficient of nodal vertical displacement becomes smaller and more equally distributed, which demonstrates that PDSLSs are less sensitive to fluctuating wind effect than common latticed shell structures without cables. Finally, based on the envelopment concept and with the maximum dynamic and average wind-induced displacement responses as control indicators, the calculating method for global wind vibration coefficient (GWVC) of PDSLSs is proposed and the value with usual design parameters is given. Meanwhile, when the structure is made static analysis by means of the equivalent static wind load obtained from GWVC, the obtained internal member force response is relatively accordant with the actual response got from time-history analysis, and is a little safer.
