“…Basaglia and Dinar [47][48][49] also conducted some tests on the behavior of purlins and applied the GBT theory into the research of purlin-sheeting systems. After Polyzois [50] had studied the effect of the sag rods on the buckling limit of the purlins, Zhang and Tong [51][52][53][54][55] proposed a theory to analysis the stress and lateral buckling problem of purlins with the top flange horizontally restrained and with one anti-sag bar at middle span sections. Hancock and Pham [56] extended the Direct Strength Method into the purlin design.…”

Compared to hot-rolled steel structures, cold-formed steel structures are susceptible to extreme winds because of the light weight of the building and its components. Many modern cold-formed steel structures have sustained significant structural damage ranging from loss of cladding to complete collapse in recent cyclones. This article first provides some real damage cases for light steel structures induced by the high winds. After that, the paper reviews research on the damage analysis and evaluation of light steel structures caused by strong winds, which include connection failure, fatigue failure, purlin buckling, and primary frame component instability problems. Moreover, this review will mention some applications of structure damage assessment methods in this area, such as vulnerability analysis and performance-based theory, etc.

“…Other researchers (Gao and Moen, 2012; LaBoube, 1986; Vraný, 2006; Wang et al, 2018; Zhao et al, 2014) provided different approaches to calculate and calibrate the restraining stiffness of the purlin-sheeting systems. A number of methods (Li, 2004; Li et al, 2012; Ye et al, 2002, 2004; Zhang and Tong, 2016) have also been published to study the effects of the rotational and lateral restraints on the stress distribution and buckling behavior of C/Z-section purlins. A Generalized Beam Theory–based approach (Basaglia et al, 2013) was also employed to evaluate the restraints provided by sheeting on the buckling behavior of single-span purlins.…”

This article presents a study on the impact of the screw location and the diaphragm effects on the buckling behavior of the simply supported C/Z-section purlins under wind uplift loadings. The diaphragm effects provided by the sheeting and the warping-torsional effect induced by load eccentricity are taken into account in the differential equations of the nonlinear twisting flexural-torsional model. The biaxial bending moments, bi-moments, as well as the flexural-torsional buckling load of the purlin can be numerically obtained with the proposed model. The global, local, and distortional buckling interaction behavior and the limit states capacities are formulated based on the modified Direct Strength Method. The effects of both the restraints provided by the sheeting and impact of the screw location on the mechanical performance of the purlins are evaluated with the proposed method. The relationship between the buckling load and rotational restraint stiffness is also provided. The proposed methodology will contribute to the assessment of buckling capacity of purlin-sheeting systems.

Lateral buckling, an essential mechanical phenomenon observed in composite beams subjected to specific external loads and boundary conditions, is influenced by various factors including cutout dimension, shape, position, and beam thickness in woven fabric laminated composite cantilever beams. The investigation focused on examining the lateral buckling behavior of beams containing two square or circular cutouts and comparing the experimental critical buckling loads of beams without any cutouts, which yielded results demonstrating a significant level of agreement. Through the experimental analysis, it was determined that square cutouts exhibit superior lateral buckling behavior when compared to circular cutouts.Highlights The effects of cutout shapes on lateral buckling analysis on fiber reinforced composites. The effects of cutout location on lateral buckling load on fiber reinforced composites. Comparison of the lateral buckling performances of fiber reinforced composites in relation to the type and position of cutouts.
