COST ESTIMATION OF HIGH PERFORMANCE CONCRETE (HPC) HIGH- RISE COMMERCIAL BUILDINGS BY NEURAL NETWORKS High-rise commercial buildings
Neural network approach is applied to establish relationships between the quantities/cost of the concrete/formwork, which is required for the structural elements of tall buildings using high performance concrete (HPC), and the design variables. Hybrid and hierarchical strategies are proposed for the cost estimation, where the feed-forward networks are adopted. After training, the neural network...
متن کاملHealthy High-rise: Ventilation Issues and Innovations
Over the past several years many issues have come to light that have highlighted the need for improved ventilation in multi unit residential buildings (MURB's). High-rise buildings, for example, are all too often connected with poor indoor air quality. When looking at this issue from the perspective of urbanism and the trend to increasing the density of our urban centres, there is a dramatic ne...
متن کاملSpace Efficiency in High-rise Office Buildings
“Given the high land values in central business sections of our leading cities, the skyscraper is not only the most efficient, but the only economic utilization of certain strategic plots. An exhaustive investigation... has conclusively demonstrated that the factors making for diminishing returns in the intensive development of such plots are more than offset by the factors making for increasin...
متن کاملCardiac strain associated with high-rise firefighting.
Although numerous studies have reported the physiological strain associated with firefighting, cardiac responses during a large-scale fire operation have not been reported and cardiac responses have not been compared based on crew assignment. The aims of this study were (1) to characterize cardiac strain during simulated high-rise firefighting, and (2) to compare the cardiac strain associated w...
متن کاملRobust Tracking for High Rise/High Speed Elevators
Jing Li David Niemann Hua O. Wang Department of Electrical and Computer Engineering Duke University, Durham, NC 27708, U.S.A Abstract This paper deals with control design for the motion control of high-rise/high-speed elevators. Two main problems, tracking and releveling, are treated in the framework of output regulation problem. By doing this, we design a single controller satisfying both perf...
