This paper presents a new type of prefabricated concrete structure system and the corresponding shear wall structure. The development status in various countries is described, advantages disadvantages as well research are analyzed.

Submit Manuscript | http://medcraveonline.com interaction of airplane body with the shell has been replaced by impulse. Such approach is justified when initial stage of interaction is described, taking that concrete structure contacts quite thin aluminum body (from 3 to 8 mm thick). In this case one does not need to calculate contact boundaries thus simplifying significantly the objective and e...

Externally bonded carbon-epoxy fiber-reinforced polymers (CFRPs) have been widely used to restore or increase the capacities of reinforced concrete beams (Meier et al., 1992; Neale and Labossière, 1997; Varastehpour and Hamelin, 1997). A typical reinforced concrete bridge deck may experience up to 7x10 stress cycles during the course of a 120year life span (Barnes and Mays, 1999), while an over...

Carbon fiber reinforced polymer (CFRP) sheets are externally bonded to reinforced concrete (RC) members to provide additional strength such as flexural, shear, etc. It has been widely accepted that carbon fiber reinforced polymers (CFRPs) can be used effectively to strengthen reinforced concrete (RC) members. This paper is intended to study and use externally bonded CFRP strips to repair and st...
