Effective length factors for solid round chord members of guyed towers.
… 4.57 m (15.0 ft.) long with continuous diagonal bracings welded to the chord members, while those provided by Pirod were 6.09 m (20.0 ft.) long with the diagonal bracings cut and welded to the chord members. The diameters of the chord members varied from 38.1 mm (1.5 in.) to 69.85 mm (2.75 in.) …

Techniques of seismic retrofitting for concrete structures
… techniques are addition of shear walls or steel bracings, and base isolation. All three methods are effective. Shear walls are usually an expensive solution but they are flexible in their distribution allowing them to be hidden in the architecture. Steel bracings allow for openings but their …

Comparison of three widely-used aerodynamic modifications that minimize the impact of wind loads on tall buildings
… motion of the buildings, for example dampers, bracings and outriggers etc. Aerodynamic modification, which is a passive approach, can also be used to reduce the impacts of wind loads. In this thesis, three widely-used aerodynamics modifications are discussed: 1) Shaping the corners of …

Mutual pounding of structures during strong earthquakes
… caused by impact, whereas the story bracings are required to reduce the excessive story shears or bending moments in the higher stories caused by pounding of the lower floors. It is observed that except for very soft soils, the proposed pounding mitigation scheme will increase the …

Dimensionamento plástico de edifícios de andares múltiplos, em aço
… the automatic design of column, girders and bracings. The plastic design utilizes the ductility, which is a inherent structural steel property, and the redistribution of internal forces in statically indeterminate structures that takes place when plastic hinges develop at regions of a high …

Multi-objective optimization of vertically mixed lateral systems
… lateral systems i.e. moment frames, steel cross bracings and concrete shear walls are utilized at varying elevations of the building to determine an optimal set of results. Besides analyzing structural optimality, the MATLAB algorithm developed as a part of this research paper also evaluates each …

3-D finite element beam/connector model for a glulam dome cap
… compared with the dome cap models with the truss bracings. Finally, conclusions and recommendations for future research are presented.

Interactive Topology Optimization with Hybrid Truss and Continuum Elements Types
… classic problems including cantilever beam with bracings and MBB beam. All draw-in truss hybrid topology optimized results show a more efficient design results with lower compliance and overall lower material quantity.

Modeling and stability investigation of a Glulam dome
… 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 replaced by a 3D, 2-noded, straight beam element for the second model. Purlins consist of truss elements. Flexible joints are modeled by adding connector …

Flexural Behavior of Cold-Formed and Hot-Rolled Steel Sheet Piling Subjected to Simulated Soil Pressure
… effect of different transverse stresses. Lateral bracings were provided at discrete locations to establish a sheet piling wall behavior and allow the development of transverse stresses. Load-pressure, load-deflection, load-strain, and moment-deflection responses were plotted to demonstrate the …

Seismic retrofitting of the Ste-Justine Hospital in Montreal
… walls with window openings and by steel cross bracings were compared using Etabs. The two models presented lateral displacements smaller than the deflection criterion of 1:300, but the concrete shear wall model was found to be the one generating the smallest displacements.

Innovative accessible sunken floor systems for multi-story steel buildings
… fire-rated acoustical ceilings and horizontal bracings to cut down the construction cycle and costs. A second variation of the proposed systems permits economies in concrete slab finish by using lightweight concrete poured on corrugated metal decks, or by using pour- in -place or precast slabs …
