Precast load-bearing shear wall panels are used extensively for high-rise construction because of the ease and speed of assembly, and the high quality of the precast panels. The connections between panels are extremely important since they affect both the speed of erection and the overall integrity of the structure. This paper presents the results of a research program conducted to investigate ...

The worldwide use of precast concrete frames leads to an increase in the need for the investigation of efficient precast connections, particularly in the seismic regions. The current paper provides a numerical and experimental study on a dry precast connection. Experiments were conducted to validate the finite element method in the laboratory of the University of Science and Culture. To verify ...

Prestressed, precast concrete piles using High-Strength Steel Strands (PPCPs HSSS) are a new type of pile. Compared with prestressed high-strength (PHC) piles, the adoption ultra-high-strength and HSSS not only improves load-bearing capacity, but also enhances ductility piles. The engineering application PPCPs requires high bearing capacity pile segments, reliable splicing to ensure cooperation...

Precast load-bearing shear wall panels are used extensively for high-rise construction because of the ease and speed of assembly, and the high quality of the precast panels. The connections between panels are extremely important since they affect both the speed of erection '~md the overall integrity of the structure. This paper presents the results of a four-year research program conducted to i...

BIM is a complex technology. Although its potential benefits are clear, its integration in structural engineering firms requires leadership and persistence as well as careful planning. Sophisticated threedimensional parametric modelling software for precast concrete structures has been commercially available since 2005. Early adopters have gained sufficient experience with precast concrete buil...

This paper deals with the economic optimization of prestressed concrete precast pedestrian bridges typically used in public works construction. These bridges are made of a precast concrete beam that integrates an upper reinforced concrete slab for the pedestrian traffic. The beam has a U-shape cross-section. Typical span lengths range from 20 to 40 m and the width ranges from 3.00 to 6.00 m. Th...

Previous case histories have shown that soil liquefaction severely damaged many structures supported on pile foundations during earthquakes. As a result, evaluating the potential for instability is an important consideration for the safe and resistant design of deep foundation against earthquakes. In this study, the liquefaction susceptibility of saturated sand interacting by single concrete pi...
