  Mobile Seasonal Padel Court Based on a Mesh/Grid Shell Structure Using AISI 304 Wire, PP and Aluminum Tubes, and Thermal Energy from a Containerized Mining Farm Yuriy Shevnin Independent Researcher, Saint Petersburg , Russia Email: jurishevnin@gmail.com ORCID: 0000‑0003‑6208‑7586 Abstract This article presents an innovative design for a mobile seasonal padel court intended for private plots, gardens, and small residential communities. The structure is based on a lightweight mesh shell of elliptical or anticlastic form, constructed from AISI 304 stainless‑steel wire , flexible polypropylene (PP) tubes with diameters between 20 and 60 millimeters, and rigid aluminum tubes with diameters between 10 and 40 millimeters. The system incorporates rhombic and rectangular panels , as well as a large‑mesh hinged wire network with cell sizes ranging from 100 to 1000 millimeters for roof coverings and perimeter bracing. The roof is made of ETFE film tensioned over an anticl...

Abstract This paper presents an architectural and engineering concept for droplet-shaped prestressed gridshells formed on the basis of a Chebyshev net and biomimetic design principles . The proposed structural system combines a uniformly tensioned lattice, a hierarchical central support, and localized compression elements, resulting in a lightweight spatial shell with tunable stiffness, high stability, and minimal material consumption. The methodology integrates geometric modeling , physical prototyping, and nonlinear finite-element analysis to investigate the influence of prestress on stiffness, dynamic behavior, and load redistribution. The Chebyshev net is ...
