This paper explores the possibility of applying technique magnetic orientation steel fibres for manufacturing a concrete structural element realistic dimensions, compared to small laboratory specimens. could be part an answer current need faster and automated production in prefabrication industry. The examined specimens have dimensions commonly used lintels construction, 80 mm × 100 980 mm. pro...

The post-tensioned frame is one of the recently emerged structural systems for multi-story timber buildings. It characterized by a high level prefabrication and quick erection on construction site. developed at ETH Zurich based beam–column connections with hardwood reinforcement column in connection region base glued-in steel rods. Such system suitable low- mid-rise buildings that are located r...

Abstract Ablation with ultrashort laser pulses as a surface micromachining tool was studied using hybrid die-excimer system that has high energy per pulse (tens of mJ’s), about 600 fs duration and low repetition rate (2 Hz). The effect ablation on the material microstructure this pulsed studied. Micropillars were fabricated by spot size hundreds micrometers. Two methods tested for micromachinin...

Prefabricated construction has long faced problems due to the industry’s fragmentation. Building Information Modeling (BIM) thus appeared as an efficient solution provide a favorable environment for completion of projects. Despite its benefits, implementing BIM successfully in small and medium-sized enterprises (SMEs), which represent vast majority manufacturers Quebec, requires deep risk analy...

With the increase of traffic pressure on main roads in central areas major cities, new high-speed elevated corridors have become a way to relieve urban congestion. However, for prosperous areas, cast-in-place piers and cap beams cannot be used well due long construction period harsh conditions. At this point, prefabricated cover can solve above problems. actual engineering abroad, especially Af...

With the rapid development of global economy, energy resources and environmental problems continue to deteriorate. As an industry with high consumption, sustainable construction is vital. Prefabricated housing can overcome disadvantages traditional methods such as long periods, low production efficiency, engineering quality safety, achieve goals fast construction, safety durability, carbon prot...

Abstract The objectives and solutions that become necessary, within the green digital transition, can radically interfere with existing methods for designing producing buildings portions of cities. “factory” “construction site” were one same thing, in production buildings, up until seventies last century. Following advent prefabrication, factory has gradually been separated from construction si...
