Material quantities of foundation systems in building structures
There are three major areas in which buildings consume energy: (1) energy consumption from operational processes, such as heating and electricity, (2) energy from building material production and supply, and (3) energy from design and construction processes. In recent years, improved operational …

Algorithmic planning for robotic assembly of building structures
… to program robots to assemble discrete spatial structures. Benefitting from the robot’s capacity for moving, positioning, and holding elements precisely, robotic assembly aims to neutralize the cost and time impact of increasing demand for non-standard, customized designs using programmable …

Automated Engineering Design for Reusable Concrete Building Structures
… (RC) structural system. Unlike steel and timber structures, RC components are rarely reused due to the inseparable phase between concrete and steel. This results in down cycling of the components into aggregates or landfill material. The Pixelframe structural system [1] was proposed to facilitate …

Seismic behaviours of adjacent building structures on liquefied soil
… of soil-structure-interaction, SSI) and adjacent structures (in consideration of structure-soil-structure interaction, SSSI) with shallow foundations on liquefiable soil. Consideration is given to the influence of foundation types, relative dynamic characteristics of adjacent structures, and the …

Material quantities in building structures and their environmental impact
… of embodied energy in the total life cycle of building structures. Despite a growing interest in this field, practitioners lack a comprehensive survey of material quantities and embodied carbon in building structures. This thesis answers the key question: "What is the embodied carbon of …

Aerodynamic investigation of cylindrical and y-shaped building structures
… investigation of cylindrical and Y-shaped building structures was carried out. Specific emphasis was directed towards determining the pressure distribution over three configurations: a flat top, a single dome and a dome with a counter-dome. The Y-model was tested in all three configurations …

Stochastic prediction of collapse of building structures under seismic excitations
… design provisions help enhance life safety of building occupants during a strong earthquake-shaking event by ensuring acceptably small likelihood of structural collapse. Therefore, accurate estimate of collapse likelihood of buildings under seismic excitations has recently become critical in …

Temperature effects on reinforced concrete building structures in Saudi Arabia
The effects of temperature distributions resulting from ambient conditions on reinforced concrete roofs in Saudi Arabia are investigated. A finite element program (ABAQUS) was used to determine the temperature distributions under different weather conditions. The model was verified by means of …

Passive electromagnetic damping device for motion control of building structures
… new device for the passive control of motion in building structures: an electromagnetic damper. The electromagnetic damper is a self-excited device that provides a reaction force to an applied motion. We chose a tubular permanent-magnet linear machine as this new structural damper, and we derive …

Nonlinear three-dimensional behavior of shear-wall dominant reinforced concrete building structures
… reinforced concrete shear-wall dominant building structures commonly built in Chile, Japan, Italy and Middle East countries are investigated. Because there are no beams or columns and the slab and wall thickness are approximately equal, available codes give little information relative to …

Shear wall layout optimization of dynamically loaded three-dimensional tall building structures
… results. Every time the stiffness of the building is modified, the structural designer must ensure deflection and inter-story drift limits are respected followed by flexural, shear and torsional strength checks for each shear wall. A computational optimization framework has the potential …

Low carbon pathways for structural design : embodied life cycle impacts of building structures
Whole life cycle emissions of buildings include not only operational carbon due to their use phase, but also embodied carbon due to the rest of their life cycle: material extraction, transport to the site, construction, and demolition. With ongoing population growth and increasing urbanization, …
