Stability of precast reinforced concrete structures

The aim of the precast work is to study the stability of precast concrete structures specially large panelstructures these structures includes planes of weakness which are the joints , The main problem associated wlth the desiGn of large panel elements structures are discussed , Atheortical study with finte element method for evaluating the effect of joints on the behavior of leroe panelstructures have been (:13.1:’1’ i ed ou t u s i ng arnod if i eel .:”:·mplJt el’program I.
