Abstract: The installation of new opening is necessary for remodeling project, house merging type. Current structural design code cannot provide the deterministic way for designing the shear walls with openings. So many engineers prefer to retrofit the perforated wall area for the structural safety. For the safe design of retroftitting, for the perforated structural walls, we carried out nonlinear finite element analysis to find the coupling effect of remaing walls. Specifically, many types of shapes were considered and various area of rectangular openings were analyzed. For the effective retrofitting, door shape and such area about 20% of wall is appropriate for retrofitting of reinforced concrete shearwalls.

Abstract: New interdisciplinary material and manufacturing technologies make local configuration of material properties possible. The availability of material property information in the early construction process and adequate welding technologies are essential needs to realize a maximum utilization of material. The research objective of two cooperating institutes at the Technical University of Clausthal is to develop a design strategy with related design rules in order to engineer high strength coupling elements of requirement optimized composite materials. Special attention is paid to the usage of future welding technologies and their influence on material properties of locally altered materials. Further objective is an early survey of the consequences caused by the usage of locally altered materials in mixed architecture design projects to the whole production process.
