reinforced concrete structures

This article presents a study of the use of composite materials in strengthening building structures. Materials consisting of two or more components or phases are called composite. Now modern composite materials open up new opportunities for design in all areas of production. The construction industry is no exception. Laminates, canvases, nets, rebars and ropes made of high-strength fibers of various origins are among the most widely used in construction at the moment.

For ensuring sage conditions of maintenance of buildings and structures, primary importance is supporting of its due technical state, displaying of its physical depreciation and causes, which determine its technical state. The vibration, among of all types of mechanical effects, is the most dangerous for engineering structures. The destruction of structures comes by vibrational influences under conditions of resonance. This process is very fast and it comes frequently.

The System Analysis of the Eurocode 2 and project fib Model Code 2010 shows their radical disadvantage: the absence or incompleteness of links between partial and general design that in accordance with system approach means the insufficiently high level of those designs development, caused by the absence of the enough General Theory of Reinforced Concrete (RC). It is stated the essence of the General Theory of RC taken as a principle of the more perfect ADM model Code for projecting of RC Structures.
