Progressive collapse accidents of single-layer latticed domes seriously threaten public safety. The progressive collapse-resisting capacity (PCRC) is gradually becoming an essential requirement in the design of spatial structures. Currently, the joint system u...

The aluminum alloy reticulated shell structure of Nanjing Niushou Mountain, the largest single-layer aluminum alloy reticulated shell in Asia, is 227m long from south to north, 130m spanning from east to west. In the design process, the aluminum alloy reticula...

This paper presents an optimization method for incorporating discarded naturally curved wood logs onto a freeform gridshell with a predefined topology. Though still little explored, the research field of reusing structural elements is experiencing increasing a...

Recent developments in applied algebraic topology can simplify and extend results in graphic statics – the analysis of equilibrium forces, dual diagrams, and more. The techniques introduced here are inspired by recent developments in cellular cosheaves and the...

Stress flows in a predictable pattern, and structural optimization is achieved by matching the natural flow of stress with the structural shape. The geometry of the parabolic shape simulates the natural flow of stress, and is therefore highly efficient in the ...

Inspired by the traditional notched planar reciprocal frame (RF) that uses short elements to build load-bearing structures with a span longer than individual elements, we search for an innovative way of using salvaged timber for building RFs specifically conne...

NURBS can create free-form shells by specifying a number of control points and their weights. However, it is challenging to create a form that strictly passes through all the specified control points even with increased weights. This paper proposes an initial-...

With the development of technology and the materials used, shell structures have developed into more complex forms. This article is a comparison between contemporary and historical shell structures. The change is an effect of the evolution in the design proces...

The transverse out-of-plane response of the RC moment frame on the arena floor damaged a school gymnasium that was expected to function as a natural disaster shelter. It was composed of heavy RC substructure and a light steel roof, which partially collapsed, r...

Tensegrity structures are typically composed of bars and cables held together in a state of self-stress. This introduces a challenge regarding the practical use of tensegrity structures, as many structures in civil engineering, such as bridge decks and roof co...

Focusing on the free-form reticulated shells with semi-rigid joints, a stability study is conducted in this paper. Firstly, the gradient-based optimization and genetic optimization are conducted respectively, by which the local optimal shell and the global she...

This paper proposed and studied the method of simplifying concrete substructures of the suspen-dome prototype structure in shaking table test scale model. Firstly, a method that replaces complex concrete substructures of the suspen-dome prototype structure wit...

The article presents the technical solutions implemented during the design of the roof trusses and the elliptic skylight structure (Figure. 1) for the extension of the "Shopping City Sibiu" commercial centre in Romania. The area of the roof structure was appro...
