Modular constructions made of UHPC [PDF]

, 2013
CNC-machine. The dry joints of the arch construction remain under compression in SLS. The assembling of the arch lasted only two weeks by applying swivel-in method of arch construction. For the design of the arch the development of new calculation models and a lot of experimental tests including also full scale tests was required.
