A Hysteresis Model for Reinforced Concrete Space Frame Structures
A hysteresis model to simulate the behavior of reinforced concrete columns subjected to biaxial bending and varying axial load is proposed. The model, identified as the U-model, is based on cross-sectional properties. The U-model combines the Otani's modification of the Clough model and the Ziegler …

THE EFFECTS OF CURRENT BLOCKAGE ON OFFSHORE STRUCTURES
… the problem of hydrodynamic forces on fixed space-frame structures in combined waves and an in-line steady current. Because of current blockage, the actual drag force experienced by such structures is over-predicted by the standard Morison equation and the present industry standard practice. …

An analysis of shells by a framework analogy
… extended to shells. The analogous structure is a space frame composed of pin jointed members which represent the shell and stiff jointed members which represent edge beams or stiffening ribs. It is analyzed by the displacement method. Effects due to foundation settlement and temperature change are …

Design approaches to structural optimization
… grid structures, widely known as 'space frames', possible configurations are explored which maximize the load-bearing capacity of the system in relation to its weight. The study has been organized in two chapters: The first chapter starts with a brief review of structural concepts. …

An investigation of an existing aluminum lattice dome under snow loads
… program STAAD-III. The dome was modeled as a space frame with the joint member stiffness range from pinned-end to four times the member stiffness. The internal forces in the pinned-end and framed-end models were compared to the specifications by the Aluminum Association. The pinned-end model …

Vibration Serviceability of Long Span Slender Floors
… used for long span floors are plane trusses, space frames and space grids. These types of structures are generally lighter and stronger because individual members carry externally applied loads mainly through tension and compression which makes them more structurally efficient than solid-web …

Modeling and stability investigation of a Glulam dome
… At first, linear and nonlinear analyses of a space frame are carried out for four load combinations of dead load and snow load. The results are applied as a basis for the modeling of flexible joints and bracings. Then, the 3-D, 3-noded, curved, isoparametric beam element in the first model is …
