Abstract |
The progressive destruction is the fraction or destruction of the whole part of the structure due to the incompetency of a part of the structure which is damaged and does not have the capability to distribute overload to maintain the structure’s stability. One of the main reasons of destruction of concrete structures is seismic effects and sudden loads, which are regarded as the progressive destruction of buildings. The progressive destruction is not a linear process; therefore, it should be studied nonlinearly; herby, the present research is an applied and descriptive survey. In this paper, a concrete structure of 7 floors in Tehran with high seismicity is analyzed according to the 2800 regulations as well as the concrete regulations of Iran. Moreover, the lateral obstruction system of the structures is located in dual system with a folding frame and a concrete shear wall. The sap2000 software would be used to analyze the procedure. Results demonstrate that the occurrence of a series of breakdowns in the structure, including the destruction of a linear load bearing member like column, increases the imposing effect of load on other columns; consequently, there would be more basic cuttings during the earthquake. Also, shear walls play a pivotal role in counteracting the earthquake side forces in extended concrete structures; the manner of designing, selecting the appropriate openings as well as the construction’s architecture is considered highly crucial for the building. |
