Application of damping in high-rise buildings
… to be an efficient lateral stiffness system for high-rise buildings under static loadings. The purpose of this thesis is to research the incorporation of viscous dampers into the outrigger system to improve the dynamic performance. This study will be conducted on a typical high-rise structure in …

Modal pushover analysis for high-rise buildings
… analysis is mostly limited to low- and medium-rise structures in which only the first mode is considered and where the mode shape is constant. The modal pushover analysis is shown to have a superior accuracy in evaluation of seismic demands for higher buildings, especially for story drift …

Analysis of framed-tube structures for high-rise buildings
All the previous works on Framed-tube structures required the services of a digital computer of reasonable size to obtain a solution. There appears to be a distinct need to develop a simple method which will enable hand-calculations to be carried out rapidly in the early stage of design to give a …

Seismic Fragility Assessment for Reinforced Concrete High -Rise Buildings
… fragilities are the first published for high-rise RC buildings, thus they fill an important void in regional earthquake impact assessment in Metropolitan communities. The inelastic dynamic analyses for the fragility assessments are undertaken using a simplified lumped-parameter model that …

Application of knee-bracing system on high-rise buildings
The need and ambition of humanity to go higher and higher is something that is amplified as time evolves. It is the same need that leads engineers to push their structures to higher limits. However, when engineers design higher structures their knowledge and their abilities are challenged. In that …

Parametric analysis of progressive collapse in high-rise buildings
… types of events have been predominant in mid to high-rise buildings under both accidental and intentional circumstances. The dire consequences associated with these types of buildings have fueled research efforts into preventative measures for progressive collapse. Three main design methods have …

Structural performance of early 20th century masonry high rise buildings
Early generation high rise buildings built between 1890 and World War 11 represent a technical transition between traditional load bearing masonry construction and modern curtain wall systems, and are typically referred to as 'transitional masonry buildings'. These structures comprise a large …

Trends and innovations in high-rise buildings over the past decade
Over the past decade, high-rise buildings in the world are both booming in quantity and expanding in height. One of the most important reasons driven the achievement is the continuously evolvement of structural systems. In this paper, previous classifications of structural systems are summarized …

Building Envelope Wind Pressure Manipulation for Application in Streamlined High-Rise Buildings
… for application in the natural ventilation of high-rise buildings. CFD simulations are employed to predict the wind pressure distribution around the building envelope. First, a 2-D CFD study is conducted to explore various techniques of manipulating the building envelope wind pressure …

Investigation of shear lag effect in high-rise buildings with diagrid system
… heights. The most efficient building system for high-rises has been the framed tube system. However, the framed tube building suffers from shear lag effects which cause a nonlinear distribution of axial stresses along the face of the building. A particular structural system called a diagrid …

Optimising BIPV in High-Rise Buildings in Hot Climates: A Parametric Study and Design Tool
… photovoltaics (BIPV) offer strong potential for high-rise buildings in hot climates, but practical adoption remains limited. This thesis investigates how structural parameters affect the natural ventilation cooling and electrical performance of high-rise BIPV systems, and develops a practical …

Urban Gallery
Since the dawn of high-rise buildings, human relationships have been limited by the floors. Compared to the pre-industrialized era where residential streets fostered community socialization, it is safe to say our relationships are constrained to the physical boundaries that surround us. Especially …

THE EFFECTIVENESS OF WIDE COLUMN LUMPING METHOD FOR PRELIMINARY DESIGN OF HIGH-RISE BUILDING
… pressure on limited space have considerably made high-rise buildings used as feasible solution for housing and commercial needs. However, there are many complex and indeterminate problems, especially analysing high-rise building at the conceptual design stage. As pointed out in several researches, …
