###### Abstract
[8] researched the fatigue characteristics of a corrugated metal roof under the action of a simulated tropical cyclone by combining the wind tunnel pressure and cyclic load tests, counting the damage accumulation of metal roof claddings, and comparing the calculated results with the results of low and high three-level loading sequence tests of TR440 [9]. [PERSON] [10; 11] summarized the wind-induced damages of low-rise buildings in Australia for years, and proposed that the roof panels are often damaged under the action of strong winds; this resulted from insufficient strength of the joint parts or from wind-induced fatigue. The author further reviewed the fatigue loading sequences of various countries. Based on the wind tunnel test pressure data of a typical house model and the wind speed and direction data of a typical simulated cyclone, the LHL four-level load cycle sequence is proposed to simulate the action of a cyclone, which is the ELCS closest to the actual situation in existing fatigue testing sequences. The current fatigue design of metal roof in Australian cyclonic regions is based on the LHL loading sequence specified in the National Construction Code [12]. [PERSON] et al. [13] used ABAQUS software to analyze the damage of the finite element model of aluminum alloy roofing system standard specimens under the action of eight load sequences in the load cycle, as recommended by CSA. According to the damage results obtained from numerical analysis, a simplified load sequence based on a CSA-recommended load cycle was proposed.

The wind resistance performances of metal roof systems are complex. [PERSON] et al. [14; 15] studied the low-cycle fatigue response of a corrugated metal roof cladding by subjecting cladding specimens to a series of static, cyclic, and simulated tropical cyclone loadings. They pointed out that the peak value of cyclic loading and the corresponding amplitudes are the main determinants of the generation and development of fatigue cracks. When the cyclic loads exceed the local plastic deformation load of cladding, the number of cycles to failure is significantly reduced. [PERSON] et al. [16] investigated the mechanism of fatigue crack initiation in roof cladding, and established a fatigue crack initiation criterion based on strain. [PERSON] et al. [17; 18; 19] investigated the fatigue performance of metal roof batten to purlin screw fastener connections, and proposed fatigue design equations for crack initiation and complete failure of roof batten to purlin connections. [PERSON] et al. [20; 21] studied roof batten' pull-through capacity by using experimental methods and numerical analysis; they provided design criterion and capacity reduction factors for the pull-through capacities calculation of roof batten. [PERSON] et al. [22] used experimentation and simulations to analyze the wind-resistance performance and failure pattern of the 360\({}^{\circ}\) vertical seam-locked metal roof system, and proposed a method to improve the wind resistance of metal roof systems. It is important to analyze and predict wind-induced damage for long-span roofs. [PERSON] et al. [23] used a numerical analysis model and measured wind pressure-time history to evaluate the reliability of roof panels exposed to a specific hurricane event. They proposed that finite element analysis can be simplified by using a series of sequential linear-elastic static analyses. [PERSON] et al. [24] proposed a probability analysis method for wind-induced damage of metal roof claddings based on wind tunnel test data, and used the Copula function to study the influence of wind load correlation on roof damages.
