The plate-column joint (PCJ) is a kind of typical semi-rigid joint improved from traditional plate joint and has larger bending stiffness. The influence of the geometric parameters of the joint on its bending stiffness and the stability of its semi-rigid retic...

Origami models are often idealized by discrete folding of zero-thickness sheets; however, the sheet thickness and the elastic limit of the material cannot be ignored in engineering practice. One solution for realizing thickness is the compliant hinge, which re...

Inflated membranes are flexible structures and very sensitive to wind load. Wrinkling deformation of the enveloping membrane can further intensify the trend of wind-induced damage. This paper aims at studying the effect of wrinkling deformation on the bearing ...

While the hanging model and physical prototyping are reliable methods for form-finding continuous lightweight shell structures, they cannot explore various design possibilities and consider multiple criteria in the design. This research aims to employ metaheur...

Several structural systems rely on a specific hierarchy between their constitutive elements, which results in topological constraints on the feasible patterns that can describe them. Folded, corrugated, or creased surface structures require this bipartition, a...

Deployable structures made of elastic materials connected by rotational pivots that transform from a flat state to a curved surface have advantages such as being lightweight and construction efficiency. In particular, the geodesic grid shell, in which flat mem...

Development of new timber construction techniques has mainly focused on the hybridization of wood with other materials to improve the bearing capacity through integration with steel plates and fasteners. The advantages of embodied carbon in wood constructions ...

Robotic coreless filament winding with natural fibres and bio-based resin systems offers potential solutions to address productivity and sustainability challenges in the construction sector. Their use in modular, prefabricated structures enables efficient, con...

Structures with deployable and compliant mechanisms are new to the domain of underground geotechnical systems. An anchor with rotationally deploying compliant thin-wall elements has been developed. This paper presents variations of this anchor that are targete...

This paper describes the pioneering original design and construction of the 1960s historic concrete shell structure of the Smithfield Poultry Market Roof in London, and the sophisticated and innovative method used to breathe new life into this unique structure...

This paper presents a new in-plane design of non-circular triangulated tensile spoke wheels with two perpendicular symmetry axes, like those used for roofing big sports stadiums, as well as a procedure to define such design. The proposed procedure describes ho...

The cable-net formwork method has attracted attention as a low-cost and environmentally friendly way to realize free-form concrete shells. In this method, the doubly-curved surface of the membrane is controlled through wire end position and tension; Block Rese...

In the literature, reciprocal frames have been studied mostly for static structures. Studies on kinetic reciprocal frames are very limited. This study investigates two degrees-of-freedom reciprocal frame fans, and a novel deployable reciprocal frame network is...

The following article presents the study and further development of the roof system developed and patented by Friedrich Zollinger in 1920. The so-called Zollinger construction system is based on short timber components ‐ lamellae, connected by a bolt and a for...

The importance of digitally archiving existing architectures for cultural and research purposes is continuously increasing. Therefore, there are growing needs to extract significant data and reduce the amount of data in 3D measurements. Point clouds obtained f...

Air-supported membrane structures are widely used. The stiffness and shape of such structures depend on the pressure difference between indoor and outdoor environments. As the leakage of indoor air may lead to the collapse of the structure, it is necessary to ...

Due to its elegant appearance and high structural efficiency, free-form grid structures are increasingly adopted in architectural design. However, it is a challenging task for engineers to generate a uniform and well-shaped grid on a free-form surface while co...

In 2021, five silos for grain storage were ordered, delivered and mounted for expansion of a warehouse in southern Bulgaria. They were produced of thin-walled galvanized sheets. The sheets were corrugated to prevent local loss of stability. All elements were j...

In this study, the mathematical model referred to as the panel-pin model is proposed for analyzing the infinitesimal-deformation mechanism and the large-deformation equilibrium path of a rigid origami composed of rigid faces (panels) and subjected to deformati...

We introduce a novel family of structures that can be inflated from a plane to form a three-dimensional surface using articulated straight pouches with inextensible membranes. Specifically, we propose a modular design using a quadrangle surrounded by four slen...
