Influence of Turbulence on the Aerodynamics of Low-Rise Buildings
… aims to determine the roof pressures acting on low-rise buildings with consideration of the effects of turbulence (terrain). Pressure measurements, as well as wind speed data, were taken at the Boundary Layer Wind Tunnel Laboratory (BLWTL) of the University of Western Ontario (UWO) to examine …

Wind flow characteristics and their effects on low-rise buildings
Two fundamental flow phenomena, the separation bubble (SB) and conical vortex, over the roof (flat and rectangular) of the Texas Tech test building are studied in terms of flow characteristics and pressure-generating mechanisms. Major fmdings contribute to understanding the mechanisms of pressure …

Technical factors influencing decisions to recommend underpinning of low-rise buildings on shrinkable clay
Foundations to buildings which fail, are frequently underpinned and since 1971 whenhouse insurers began to offer cover for damage due to "subsidence", the underpinningindustry has grown to enjoy a multi-million pound turnover. Much of England southeastof a line from the Humber to Exeter, has a …

Seismic Design Studies of Low-Rise Steel Frames
In this investigation, the inelastic behavior of low-rise buildings with steel moment-resisting frames providing the lateral resistance for strong ground motions was examined. The inelastic behavior of frames is dependent on several parameters such as design base shear, beam-to-column strength …

Validation of CFD Tornado Pressure on Building and Wind Field with TTU Vortex Chamber Measurements
<p>Structural failure of low-rise buildings is the root cause of higher number of casualties, death tolls and economic losses at the place of occurrence of tornadoes. Proper design of low-rise buildings in tornado-prone areas require accurate estimation of tornado-induced wind loads; however, …

Performance of snug tight bolts in moment end-plate connections
… end-plate connections for use in single story buildings. Wind loading was deemed to be the critical loading on snug tight bolt, moment end-plate connections. A test loading sequence was established based on a statistical analysis of the 50-year wind loading on low rise buildings. Eleven …

Seismic retrofitting of deficient Canadian buildings
… earthquake loading, such as unreinforced masonry buildings, flat slab concrete buildings and steel frame buildings. It then presents the most common retrofitting strategies applicable to low-rise buildings commonly found in major Canadian cities. A case study assessing the performance of hybrid …

Parametric study of timber shear walls
Timber shear walls comprise the vertical element of the lateral force resisting system in many low-rise buildings in North America. A typical shear wall consists of a solid panel product connected to a light timber frame with either a dowel-type fastener, such as nails, or elastomeric adhesives. …

An industrialized housing system,
… pace with the increased housing demand and for lowering construction costs. Our approach was to minimize the work that would have to be done on the site and increase the factory process, thus eliminating inefficient on-site labor. We recognized transportation regulations and building codes as …

Improved seismic analysis of unreinforced masonry buildings with flexible diaphragms
… diaphragms in many existing unreinforced masonry buildings poses a significant challenge for the assessment of their seismic vulnerability. When diaphragms are flexible, different parts of a structure can interact with each other dynamically, in a way not typically encountered in modern structures …

Terrace housing : providing quality in higher-density housing
… methods has changed the forms of housing from low-rise buildings to multistorey apartments. During the last two decades, people in Bangkok have faced problems of living in high-density housing and lack of open space, which limit the quality of living space. Providing better quality of living …

Sensitivity of Steel Purlins to Changes in Application of Wind Loads
… of wind tunnel test loads applied to purlins in low rise steel buildings compared to those determined with currently recognized wind loading provisions. The National Institute of Standards and Technology (NIST) database of low-rise building wind tunnel test data, which was collected at the …

A study on ground improvement using a combination of stone and concrete columns
… technique that is typically employed for low-rise buildings and road embankments. This technique mainly uses naturally occurring materials as its load transferring medium. However, stone columns have some constraints because of the loose interactions between their aggregates which can lead …

Investigation on the effects of the wind vertical angle of attack and the wind speed profile on low-rise building pressures and its implications for wind loading by severe convective storms
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2022-11-14 without embargo terms

Wind-Induced Pressures in Air Permeable, Double-Layer Roof Systems in Regions of Separated Flow
… permeable, double-layer roof systems placed on low-rise buildings. Because of the pressure transmission into the cavity between layers, the pressure difference in the double-layer systems differs significantly from that in a single layer. The interior pressures (in the cavity between layers) are …

Investigation of Modular Cross-Laminated Timber Rocking Walls and Rocking Wall -- Light-Frame Shear Wall Dual Systems for Seismic Resilience
… were designed to replicate the first story of low- to mid-rise mass timber buildings. Two of the walls included a laminated strand lumber (LSL) toe reinforcements aimed at preventing localized crushing damage upon rocking. Several key design parameters were considered, including wall aspect …

Aging in seniors' multiple housing in the Vancouver area : a comparative study of three organizations
… there are differences by building type (high/low rise) or by organization. Case studies of three seniors housing organizations are presented; New Vista Society (NVS), British Columbia Housing Foundation (BCHF), and British Columbia Housing Management Corporation (BCHMC). Data on median age of …

Parameters Influencing Seismic Structural Collapse with Emphasis on Vertical Accelerations and the Possible Related Risks for New and Existing Structures in the Central and Eastern United States
… using bilinear SDOF models representative of low rise buildings in both the Western United States (WUS) and the Central and Eastern United States (CEUS). Models were created that represented three, five, seven, and nine story buildings. Five sites from both the WUS and CEUS were used. Four …
