Üsküdar University Faculty of Health Sciences Deputy Dean OHS expert Dr. Instructor Member Nuri Bingöl evaluated the precautions to be taken against possible earthquakes in high-rise buildings.
Reminding that floor selection is important in high-rise buildings, Dr. Nuri Bingöl said that first of all, a risk assessment should be made by collaborative work according to the engineering discipline related to this issue.
Soil mechanics and behavior should be well studied
Noting that the priority is to build multi-storey high-rise buildings on geologically sound soils, Dr. Nuri Bingöl said, “However, considering the fact that there is no solid ground in every region and that our country is an earthquake country, it is not always possible to find solid ground. In this case, with advanced construction technologies, it is possible to construct multi-storey buildings by choosing ground reinforcement and reaching solid ground methods such as piling and shutcrete application so that the building foundation reaches solid ground. Therefore, soil mechanics and behavior should be well studied at the planning and project stage, and a multi-storey building should be built according to these investigations. Suspension of possible tremors by using earthquake isolators will also be good examples in practice.” made its assessment.
In high-rise buildings, the project must be fully complied with.
Touching on the points to be considered in the construction of high-rise buildings, Dr. Nuri Bingöl said, “The building should be designed by making the most accurate static calculations in accordance with the relevant legislation, standards and civil engineering science in the construction of high-rise buildings, and this project should be strictly followed during the construction process, especially the concrete class used in reinforced concrete structural elements such as curtains, columns, beams, floors. It should be ensured that the project is implemented with sufficient and effective supervision by the building inspection institutions, without making any concessions on the application and curing of the reinforcing steel in the appropriate class and in sufficient physical conditions.” said.
It is important that the contractor company provides the engineering services correctly.
Stating that the contractors of high-rise buildings should be competent and qualified to implement this project, Dr. Nuri Bingöl said, “In addition to external audits such as building inspection, the contractor company will provide accurate engineering services, constantly monitor its internal audits and applications, and, if necessary, with on-site interventions, it will prevent many situations such as mistakes, lack of connection, and reinforcement problems. The problem of insulation of building foundations is also important. In this regard, the situation should be kept under control by taking engineering services at the beginning of the work very carefully during the project phase and foundation construction so that the ground or basement floors, namely the foundation, do not get water in the future.” he said.
Horizontal architecture should be preferred
Stating that buildings should not be built as high-rise in areas where liquefaction occurs, Dr. Nuri Bingöl said, “It should be a priority to do it in accordance with the engineering requirements. Fulfilling the requirements of science and science is important in all conditions, including buildings to be built on liquefied soils. Engineering applications should be used in accordance with the ground. Horizontal architecture should be preferred. According to the condition of the ground, engineering calculations and application techniques can reveal how many floors the buildings can have under similar conditions. used the phrases.
Compliance with regulations and standards reduces risks
Noting that any building constructed in accordance with the technique in a way that will meet the project conditions prepared in accordance with the relevant legislation and standards, under minimum conditions, will not pose a danger regardless of floor height. Nuri Bingöl said, “Even a single-storey building that does not meet these conditions poses a danger. Fulfilling the engineering requirements can be done in high-rise buildings in a way that can withstand high vibrations during earthquakes, provided that they are built in accordance with the standards. Let's not forget that there are many buildings built on steel construction. As long as it is supported with earthquake isolators during its construction, the shaking levels in high-rise buildings will decrease and these high-rise buildings will withstand these low-level shocks.” he said.
