Research Progress on Curved Plates in China: Applications in Architecture

Abstract

Curved surfaces can give plates a unique aesthetic effect and physical advantages in acoustics and optics. Assembling such curved plates can greatly improve the image of buildings and enrich their functions. It is thus not surprising to notice that their wide applications in designed or completed buildings in China have become a trend. Thus, this study offers a comprehensive summary of the application progress of curved plates in the architectural field from three aspects: image expression, acoustic characteristics, and optical characteristics. On this basis, future directions are proposed. The main findings or suggestions are as follows: (1) climate harshness has increased recently, and the safety of structures and materials and the coupling effect of the two must be fully considered when designing the shapes of curved surface buildings; (2) research on the mechanism and numerical calculation of curved diffuser systems with different sizes and curvatures needs to be further developed; and (3) experimental studies of various and complex curved plates and different conditions to explore their optimal reflectivity, transmittance, absorptivity, and other optical properties will be an important development direction.

Load-bearing behaviors of sandwich plates with non-uniformly distributed grid cores: Dynamic impact and blast

“…The utilization of sandwich structures, particularly grid-core sandwich plates, has become increasingly widespread in fields such as aerospace [1,2] , transportation [3] , and beyond [4,5] , owing to their remarkable attributes like high strength-to-weight ratio, stiffness, and energy absorption capacity. In these domains, especially where dynamic impact and blast resistance are crucial [6] , the in-depth optimization of such structures assumes a paramount importance [7,8] .…”

Clamping method and mechanical properties of aluminum honeycomb cylindrical curved plates under radial compression

“…11 Therefore, bending the flat sandwich plate into a curved one is an effective way to concentrate strengths and quickly optimize the structural performance. 12 There have been studies on the mechanical behavior under radial loading of curved plates with different core layers, such as polyurethane foam cores, 13 pyramid lattice cores, 14 and foldcores. 15 To more scientifically and effectively utilize the indexes to reflect the mechanical behaviors and compare different structures, the establishment of a rigorous and effective test system has become an urgent problem to solve and a prerequisite for the systematic study of mechanical properties.…”
