Masonry is probably the oldest and one of the most widely used man-made construction materials in the world (Ganz 1990; Bean Popehn and Schultz 2003; Drysdale and Hamid 2005). The major advantage of masonry is that in terms of raw materials it is highly available worldwide and in terms of construction it is easy and […]
Prestressed concrete can be defi ned as concrete in which internal compressive stresses are deliberately introduced so as to counteract the tensile stresses (and consequent cracking) resulting from external loads to a desired degree. In simple words, a precompressed concrete is known as prestressed concrete. In concrete members, the prestress is commonly introduced by tensioning […]
Creative design of bridge structures requires new approaches for digital fabrication and accurate geometry control during construction. This paper deals with prefabricated bridge piers which have unique creative shapes. 3D design models were created to realize irregular column shapes. Economic formwork for the precast column segments was provided by 3D printing technology. Panelized formworks were […]
