| Abstract | ||
| In modern construction, after the completion of the concrete structure, there are many openings and Ducts necessary for many services . the openings in the prestressed concrete beams became an important parameters must be studied. In this work, the behavior of prestressed concrete beams with opening was experimentaly and theortically studied. The effect of opening size, timing of created openings, and type of section are the main paramters The experimental study consists of six prestressed concrete beams with rectangular crosssection, sized 200 mm (width) x 400 mm (height) x 4000 mm (length) were manufactured, one of them with T- Section (total width of Flange 600 mm). by using ANSYS program, the size of opening after validation model was studied | ||
