چکیده

Execution problems of existing concrete structures and their improvement and continuous movement of science in the field of earthquake engineering have led to modernization and upgrading in recent years using modern methods and new materials that have not had a long history of construction. Among these innovations, FRP (Fiber-reinforced polymer composite material) has a special place. Strengthening of structures has been of great importance for many reasons. This thesis, in view of the importance of this issue, is one of the general and widely used methods for enhancing FRP in a laboratory. Based on the results it can be deduced that increasing the ratio of water to cement decreases the compressive strength of concrete samples. The FRP reinforced layer under load, with the enclosure property in the concrete sample, from one place to another, creates a high stress concentration, such that the type of failure ranges from soft to crush failure, and in the objective observation it even goes beyond crushing and exploding In water, cement is 0.45 up. In fact, although the resistance in terms of resistance is of particular benefit to concrete, the type of failure that is explosive and does not give the inhabitants of concrete structures the opportunity to exit during a crisis is one of the issues that should be addressed.

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
