... in building elements substantially, thus also reducing their embodied carbon dioxide footprint. In particular, the research focused on segmented thin concrete shells as floor slabs, leveraging computational design and digital fabrication methodologies to automate their production off site. An important part...

...Ali Aghazadeh Dizaji; Mahmut Kiliç; Mahyar Maali; Abdulkadir Cüneyt Aydin Thin-walled shell structures are characterised by a lightweight structural form with high strength. The importance of using cylinders and cones has long been known to engineers and designers in various engineering disciplines...

... dynamic analysis was employed in an Abaqus platform using the lateral seismic excitations. Different patterns of random geometric imperfections of various amplitudes were considered in the tank models. The Budiansky–Roth procedure was followed to calculate the buckling capacities of tank shells...

...Mohammad Rezaiee-Pajand, PhD; Amir R. Masoodi, MSc; Elias Arabi, PhD A six-node triangular shell element was developed to study the geometrically non-linear behaviour of open-section members. The present formulation is free from shear and membrane locking due to use of mixed interpolation...

... in Spain. It is the first permanent elastic timber gridshell to be built in the country and the first in the world to be made of Eucalyptus globulus Labill. It includes various novelties for timber gridshells, such as a long-shell structural concept supported only on its short sides and the use...

...Hadi Sabermahany, MSc; Massood Mofid, PhD; Niloofar Daneshmand, MSc This study deals with the geometrically non-linear vibration analysis of concrete shallow funicular shells of rectangular plan with four clamped edges under impulse loads. The shape of a concrete funicular shell...

...Alireza Javid, MSc; Massood Mofid, PhD A special type of shell structure – a concrete shallow funicular shell of circular plan – is considered in this paper. Funicular shells carry their dead weight only by in-plane compression forces. Numerical analysis of funicular shells was performed using...

.... In this work, fragility analyses of pre-code and retrofitted tanks were conducted for existing broad tanks. The effects of steel corrosion were considered in the fragility analyses and 250 tank–earthquake non-linear analysis cases were considered. The results of the study revealed that shell corrosion...

... of this study is confirmed both by the published literature and by Ansys shell theory. Available dynamic theories for thin-walled curved beams are quite limited. Focused on the effect of shear deformation together with rotatory inertia, Krishnan and Suresh (1998) obtained a cubic linear element for static...

Co-operation between design team partners to combine their experience leads to successful building structures. The paper discusses the key issues in the design of shells, giving...

...A. Vafai; H. E. Estekanchi; M. Javidruzi Prefabricated funicular shells were constructed using a stretched membrane as a mould. Forty-five shells with various rises and different types of reinforcement were loaded to failure and their behaviour in the elastic and non-linear range was investigated...

...Y. B. Chen, PhD; Q. S. Li, PhD; J. M. Chen, PhD This investigation is concerned with the free vibration and seismic response of single-layer cylindrical lattice shells. The effects of basic structural parameters such as the ratio of rise to span, mass, damping, the ratio of length to span...
