“…While initial focus was on developing methods for achieving buildings systems with greater earthquake resistance (e.g., Moehle and Deierlein (2004)), the concepts of PBE have extended to other hazards, including wind, fire and tsunamis (e.g., Ciampoli et al (2011); Wang et al (2012); Attary et al (2017). Furthermore, the successful development of performance-based seismic engineering (PBSE) and its adoption in codes and practice over the past two decades has provided strong evidence for, not only the application of similar approaches for other natural and man-made hazards, but also riskconsistent multi-hazard design approaches (Gardoni and LaFave (2016); Suksuwan and Spence (2018); Kwag et al (2021). To successfully transfer this knowledge to wind engineering, the fundamental differences between seismic and wind effects for both structural and non-structural components, especially the envelope system, must be embraced while respecting the unique characteristics of wind loading and concurrent hazards (e.g., rainfall and debris impact).…”

This paper surveys the rapidly growing field of performance-based wind engineering (PBWE) of engineered systems, with focus on not only how PBWE has evolved since its early incarnations inspired by performance-based seismic engineering, but also the unique challenges of PBWE and the research that continues to emerge to tackle them. The limitations of traditional prescriptive wind design approaches are discussed with the aim of illustrating how such approaches are inadequate for providing acceptable building performance during extreme wind events, thus motivating why performance-based strategies for wind engineering are gaining traction and are poised to complement, if not replace, current approaches to wind design. In this respect, the current state of knowledge on the factors that affect building performance via extreme structural response, damage to the envelope system, and nonstructural components, is reviewed and challenges are identified. Lastly, the potential benefit of integrating optimization methods is identified while acknowledging the computational difficulty associated with such approaches.

“…For example, concrete is widely used in bridge structures, pile foundations, aircraft runways, dams and offshore platforms. However, these structures are subjected to various dynamic loads during their service, such as traveling loads [ 3 , 4 , 5 ], aircraft landings [ 6 ], waves [ 7 ], earthquakes [ 8 ], and other dynamic loading effects. These unavoidable human [ 9 , 10 , 11 ] and natural factors [ 12 ] present serious challenges to the safety of concrete structures.…”

Silica-fume–polyvinyl-alcohol-fiber-reinforced concrete (SPRC) is a green and environmentally friendly composite material incorporating silica fume and polyvinyl alcohol fiber into concrete. To study the impact resistance of SPRC, compressive-strength and drop hammer impact tests were conducted on SPRC with different silica-fume and polyvinyl-alcohol-fiber contents. The mechanical and impact resistance properties of the SPRC were comprehensively analyzed in terms of the compressive strength, ductility ratio and impact-energy-dissipation variation. Based on the impact resistance of the SPRC, the impact life of SPRC with different failure probabilities was predicted by incorporating the Weibull distribution model, and an impact damage evolution equation for SPRC was established. The impact life of SPRC under the action of silica-fume content, polyvinyl-alcohol-fiber content and failure probability was analyzed in depth by the response surface method (RSM). The research results show that, when the content of silica fume is 10% and the content of polyvinyl alcohol fiber is 1%, the compressive strength and impact resistance of SPRC are the best. The RSM response model can effectively predict and describe the impact life of SPRC specimens under the action of three factors.

“…Recently, many wind-resistant design methods are studied such as [1], [2], [3], and some devices are devised to suppress responses of wind loads [4], [5]. Moreover, some studies consider both seismic and wind loads to design a building [6], [7], [8]. To investigate the responses of a building for strong wind, the results of wind tunnel tests or measured data are used.…”

This paper presents a new method to estimate an along-wind load that contains a mean component using an equivalent-input-disturbance approach. An along-wind force contains both mean and fluctuating components. However, most studies estimate only fluctuating components. Moreover, these studies assume that the damping matrix is a Rayleigh one. In contrast, this paper presents a method that estimates both the mean and fluctuating components using velocity response. Furthermore, this method does not require that the damping coefficient is Rayleigh damping. The numerical verification verifies using an 11 degree-of-freedom(DOF) model of a seismicisolated building. The results presented that the presented method accurately estimates an along-wind load.
