External Reinforcement

A method of reinforcing conical reinforced concrete struts by external reinforcement with composite materials is considered. The calculation of reinforced concrete struts according to the limiting states of the first group, reinforced with composite materials in accordance with the requirements of SP 63.13330.2012 and SP 164.1325800.2014. Based on the calculation, a comparative analysis of the characteristics of polymer composite materials presented on the domestic market is carried out, rational schemes of external reinforcement of conical reinforced concrete racks are proposed, used as an AMC for installing antenna-feeder equipment for cellular communication. The results of the analysis can be used for a rational choice of polymer composite materials and reinforcement schemes for conical reinforced concrete struts.

New Methods

One of the work cycles of reinforced concrete structures is the state of repair and reconstruction, including the steps of strengthening elements. The traditional types of strengthening of reinforced concrete which are steel and concrete collars and shirts - now are receding into the background. New methods of strengthening with modern materials such as lamellae are increasingly being used. The article deals with the issues related to strengthening the structures made of high-strength concrete using composite polymeric materials.

A study review of aging polymer composite materials (PCM) under different heat-moisture conditions or water exposure with the sequential or parallel influence of static or cyclic loads in laboratory conditions is presented. The influence of tension and bending loads is compared. Conditions of the different load influence on parameters of carbon-reinforced plastics and glass-reinforced plastics are discussed. Equipment and units for climatic tests of PCM under loading are described. Simulation examples of indices of mechanical properties of PCM under the influence of environment and loads are shown.
