Topology optimization of building bracing schemes
… 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 is …

Bracing requirements for post-frame endwalls
… Fictitious members representing steel-strap bracing were added to the remaining endwall diaphragm to restore the endwall deflection to that of the same endwall with no door openings. Large corner post uplift values were observed for tall endwalls. For purposes of endwall analysis, it is …

Flange bracing requirements for metal building systems
The analysis and design of bracing systems for complex frame geometries typically found in metal buildings can prove to be an arduous task given current methods. The American Institute of Steel Construction's Appendix 6 from the 2010 Specification for Structural Steel Buildings affords engineers a …

Scoliosis Analog Model for the Evaluation of Bracing Technology
… properties provide a means to compare bracing technology and better understand design features. The testing of design alterations, i.e. variable strap configurations, show a measureable difference in brace force response and structural properties between each configuration. Also, …

Evaluation of two RC buildings retrofit with steel bracing
… The schemes were different in that one had steel bracing in the interior of the building while the other had steel bracing on the exterior of the building.

Application of knee-bracing system on high-rise buildings
… high-rise construction is the wind loading. Bracing the building in a clever and more efficient way was always a difficult task for designers and engineers. This thesis deals with a bracing system called the knee-bracing system. The application of knee-bracing system for high-rise buildings …

Mechanical bracing solutions to decrease tibial slippage of Anklebot
Anklebot is a general-purpose therapeutic robot designed to guide the human ankle through motions with appropriate assistance. Anklebot relies on accurate position feedback from its actuators, which may or may not be corrupted due to slippage of Anklebot. This study seeks to quantify the slippage …

Comparative study of bracing patterns and materials for tall timber buildings
… and carbon emission reductions for exterior bracing created in timber and timber-steel hybrid configurations. Numerical analyses are used to explore braced frame geometries and layouts for the steel and timber elements, to predict structural response, and compare the effects of material …

Elastic and inelastic responses of columns after sudden loss of bracing
… response of the column after sudden loss of bracing is analyzed using Galerkin’s method. With the consideration of the effects of the bracing location and the bracing stiffness, the maximum deflection of the column during motion is determined. The contribution of damping effects to the …

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 …

Permanent Bracing Design for MPC Wood Roof Truss Webs and Chords
… and to develop a methodology for permanent bracing design using a combination of lateral and diagonal braces. SAP2000 (CSI, 1995), a finite element analysis program, was used to analyze structural analogs for three sets of truss chords braced by n-CLB's and one or two diagonals, one web …

Comparing Optimized Perimeter Steel Bracing of Tall Buildings under Different Seismic Regions
… they had the potential to outperform traditional bracing systems under seismic excitation. This was a trend observed in multiple seismic regions in North America. This research has important implications as the use of topology optimization in designing lateral brace frames for tall buildings under …

The effect of lateral bracing on the dynamic response of wood floor systems
… 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 were …

The role of external non-rigid ankle bracing in the prevention of inversion injuries
Ankle bracing is rapidly becoming the accepted method for the prevention of inversion injuries among active individuals suffering from a chronic ankle instability. The purpose of this study was to measure the effectiveness of the non-rigid, Subtalar Stabilizer (STS) ankle brace under conditions …

Kinetic and 3D Kinematic analysis of netball movements: with and without prophylactic knee bracing
Patellofemoral pain is one of the most common musculoskeletal pain conditions, with a multifactorial aetiology. It is reported that young females are at high risk of developing patellofemoral pain. During dynamic, fast-paced games athletes are exposed to high ground reaction forces, contributing to …

Effects of Running Speed, Fatigue, and Bracing on Motor Control of Chronically Unstable Ankles
… the roles of running speed, fatigue, and ankle bracing on motor control in adults with CAI. First, two groups with and without ankle instability performed dynamic athletic maneuvers at each of two running speeds. Joint kinematics and kinetics were measured to identify differences in motor …

Analysis of Anchors and Bracing Configurations for Personal Fall Arrest Systems in Residential Construction
… truss roof system with various anchor points and bracing configurations loaded by a horizontal force. A lab built roof system was used to test three different anchor types with three forms of temporary bracing. The materials and methodology used in this testing were based on common materials and …

Investigating the Performance of Wood Portal Frames as Alternative Bracing Systems in Light-Frame Wood Buildings
… of the research is to develop wood portal frame bracing systems, which can be used as an alternative or in combination with light-frame wood shearwalls. This is done through investigating the behavior of wood portal frames using the MIDPLY shearwall framing technique. A total of 21 MIDPLY corner …
