Lateral bracing forces in compressed two-span columns with initial curvature
… of this study is to find critical loads and full bracing conditions for perfect two-span columns, and to find the reaction forces at the lateral bracing supports and maximum deflections for two-span columns with initial curvature. In each case, the column under consideration may have different …

The effect of lateral bracing on the dynamic response of wood floor systems
… of an extensive study of several types of lateral bracing for solid-sawn and parallel-chord truss floor systems. Three solid-sawn floor bracing systems were evaluated: X-bridging, full-depth solid blocking, and finally, post-tensioned solid-blocking. Five different truss bracing systems …

Topology optimization of building bracing schemes
… steel frames using topology optimization on the lateral bracing scheme. The study focuses mainly on minimizing the amount of material used and optimizing the placement of bracing elements in typical steel frame structures to achieve economical and realistic solutions. Linear structural analysis …

Net section rupture in tension members with connection eccentricity
… and similar sections are frequently used for lateral bracing and as truss elements. Such members will normally have eccentric connections, and it is often permitted, by current design specifications, to neglect this eccentricity in the design of the member. In this study, load tests were …

Optimal damping for a suspended structure under lateral loading
… the energy input on a suspended structure due to lateral loading. The specific building examined is the suspended structure that was designed by Structures Group A for the purpose of the Master of Engineering High Performance Structures Group Project, Spring, 1998. Specifically, the effect on the …

Buckling-Restrained Braced Frame Connection Design and Testing
… core extension assembly, splice plates, and lateral bracing angles. Both standard design procedures and newly developed criteria were used to design the connection. In preparation for testing, a method was developed for estimating the hysteretic response of a buckling-restrained brace. By …

Computational and Experimental Study on the Behavior of Diaphragms in Steel Buildings
The lateral force resisting system (LFRS) of a steel building consist of two parts, i.e., a vertical LFRS such as braced frames or shear walls, and a horizontal LFRS with diaphragms playing a crucial role. There are various types of floor and roof diaphragms in steel buildings, such as …

Seismic retrofit of existing reinforced concrete moment resisting frame structures using diagonal prestressing
… to increase structural stiffness and decrease lateral drift demands under seismic loading. Shallouf (2005) successfully demonstrated experimentally that a 1 bay, 1 storey R/C frame with masonry infill panels, designed based on the ACI 318-1963 building code, hence seismically deficient, could …

The Viability of Steel-Concrete Composite Girder Bridges with Continuous Profiled Steel Deck
… whether the profiled steel deck can act as full lateral bracing to the steel girder compression flange during deck placement were also made. Fatigue testing results showed that very little stiffness was lost over the course of testing at both levels of composite interaction. This leads to the …

Structural optimization: from continuum and ground structures to additive manufacturing
… interest to engineers in practice. The design of lateral bracing systems falls into this category. A novel discrete element topology optimization algorithm is proposed, and to facilitate the adoption by industry and academia, the implementation is also provided. Discrete element topology …

Lateral Torsional Buckling of Built-Up Beams
… in long-span applications without adequate lateral bracing, their strength is often governed by lateral-torsional buckling (LTB). The LTB behaviour of these systems is further complicated by the presence of discrete mechanical fasteners, which provide only partial interaction between plies, …

Lateral Movement of Unbraced Wood Composite I-Joists Exposed to Dynamic Walking Loads
… of a wood composite I-joist with different bracing configurations exposed dynamic walking loads. Three 16 in. deep GPI® 65 I-joists were simply supported and laid parallel to each other, while the bracing was attached to the top flange. Five different brace stiffnesses were used: zero …

Investigating the Performance of Wood Portal Frames as Alternative Bracing Systems in Light-Frame Wood Buildings
… been successfully used to resist gravity and lateral loads, such as earthquake and wind, for many decades. However, there is a need for maintaining the structural integrity of such buildings even when large openings in walls are introduced. Wood portal frame systems have been identified as a …

Prediction of Lateral Restraint Forces in Sloped Z-section Supported Roof Systems Using the Component Stiffness Method
… members in metal building roof systems. Lateral restraints are required to maintain the stability of a Z-section roof system and provide resistance to the lateral forces generated by the slope of the roof and the effects due to the rotation of the principal axes of the Z-section relative …
