Cast-in-Place Building Frame and Its Features at Separate Life Cycles

Abstract

Modern intensive development of precast-cast-in-place construction has led to creation of a wide range of various constructive systems of buildings during the last 100 years. They allow constructing buildings with best account of the requirements of functionality, architectural expressiveness, production possibilities of construction companies, etc. However in spite of this development both precast and cast-in-place housing construction has its peculiarities, positive and negative ones. The constructive systems of precast monolithic buildings existing at the moment are based on the required mutual deformation of prefabricated reinforced and cast iron reinforced concrete at the stage of a building construction and at the stage of its use as well. Having refused from this rule, the authors of this article have introduced a constructive system of a precast monolithic building able to bear loads, developing at the stage of erection (due to completion of a precast frame) and at the stage of use (due to completion of a precast monolithic frame). The offered construction of a precast monolithic building frame allows efficiently using the advantages of precast and cast-in-place construction minimizing their disadvantages and it also fully corresponds to the obligatory requirements to buildings. The corresponding patents are obtained.

“…Among them, the most common method is the cast-inplace method, especially in developing countries, where raw materials are easily accessed, the associated costs are lower, and this approach has been proven. However, in recent years, many countries and regions have gradually reduced the use of this construction method due to noticeable disadvantages (Abey 2019; Koyankin and Mitasov, 2015), such as a low production efficiency, waste of resources, long construction periods, and vulnerability to weather. As another option, prefabricated structures are preferred in shortening the construction period, reducing environmental pollution, reducing material consumption, complying with green construction, and following the principles of sustainable development (Alimoradi, 2015;Liu et al, 2019b;Pongiglione and Calderini, 2016).…”
