Design of high-rise concrete buildings

For many years, concrete has been used as an important building material with highpressure tolerance for the construction of various structures. The weakness of thisimportant and widely used building material against traction has been largelycompensated by placing reinforcement. In recent years, with the study of durability ofreinforced concrete structures, especially in corrosive and hard areas for concrete, theopinion of most experts and those involved in concrete work has been drawn to the factthat strength alone can not meet all the properties of concrete, especially its durability. Inaddition to the issue of strength and load bearing during operation (exploitatiom), itsdurability and permanence should be considered in the design of concrete for differentareas.Now with the addition of various concrete materials and modificationsIn the mixing design, concretes can be obtained that do not significantly change theirstrength in terms of durability to achieve high durability concretes. The issue of theenvironment and its pollution has also attracted the attention of the world in recentyears. The use of substances and materials in the construction of which less pollution istransferred to the environment and also the harvesting of natural materials that are less.Destructive to the environment, special attention is paid. In this regard, the use ofaggregates, access to new materials andAlso, the use of factory wastes and environmental pollutants in concrete is located at thetop of research programs in some countries of The world. in addition to concrete itself andits constituent materials, in recent years, changes have been made on the reinforcementused in reinforced concrete structures. For example, to avoid the risk of corrosion of theas well as reinforcements made of different plastic and reinforcement, stainless steelpolymer fibers are used in highly corrosive environments.
