Model of prefabricated concrete frame in the condition of southern Vietnam

Abstract

In recent years in Vietnam, the structure of multi-storey buildings has been strongly developed in both quantity and quality, especially multi-storey buildings made from prefabricated reinforced concrete structures. Collecting documents shows that the Mekong Delta of southern Vietnam has built many multi-storey buildings using prefabricated reinforced concrete frame systems. In the southern climatic conditions, these multi-story buildings are directly affected by climate change, especially the seasonal wind load and the intensity of the wind is getting stronger and more complex, so the the work at the nodes of the frame will be affected. In this study, the authors studied the displacement of the frame system by horizontal displacement, vertical displacement, moment, shear and axial force of the frame according to three models: rigid linked frame, joint linked frame and semi-rigid linked frame.
