Abstract

The majority of structural failures are attributable to errors in construction. This problem exists in all countries, but it is more frequent in developing communities. This study focuses on construction errors of structures in Tehran, the capital city of Iran. In this study, eighty-eight buildings have been investigated during the construction phase. These buildings have been categorized into ten types and have been distributed in twenty-two suburbs. Results showed that the buildings of Tehran can suffer from at least forty-nine major construction problems. In addition, for the first time, this research has introduced the following three terms in relation to prioritizing of construction errors: Relative Importance Factor (RIF), Priority Index (PI) and Structural Importance Index (SII). As a part of the conclusions, the results showed one hundred percent of investigated buildings are affected dramatically by the “use of untrained workers” and “lack of sampling or wrong sampling” too. In this regard, the RIF and PI of each “Lack of sampling or wrong sampling” and “use of untrained workers” are 100 and 1, respectively. Also, suburb 3 has the best construction conditions while suburb 10 has the worst.

足迹施工误差对结构的损害

大多数结构破坏是由于施工错误造成的。这一问题在所有国家都存在，但在发展中国家更为常见。本文主要研究了伊朗首都德黑兰建筑的施工误差。在这项研究中，88栋建筑在施工阶段进行了调查。这些建筑被分为十类，分布在22个郊区。结果显示，德黑兰的建筑物至少有49个主要的建筑问题。此外，本研究还首次引入了三个与施工错误优先级相关的术语:相对重要因子(RIF)、优先级指数(PI)和结构重要性指数(SII)。作为结论的一部分，结果显示百分之百的被调查建筑受到“使用未经培训的工人”和“缺乏抽样或错误抽样”的巨大影响。对此，“缺乏抽样或错误抽样”和“使用未经培训的工人”的RIF和PI分别为100和1。此外，郊区3的建设条件最好，而郊区10的建设条件最差。

期刊介绍： Engineering Solid Mechanics (ESM) is an online international journal for publishing high quality peer reviewed papers in the field of theoretical and applied solid mechanics. The primary focus is to exchange ideas about investigating behavior and properties of engineering materials (such as metals, composites, ceramics, polymers, FGMs, rocks and concretes, asphalt mixtures, bio and nano materials) and their mechanical characterization (including strength and deformation behavior, fatigue and fracture, stress measurements, etc.) through experimental, theoretical and numerical research studies. Researchers and practitioners (from deferent areas such as mechanical and manufacturing, aerospace, railway, bio-mechanics, civil and mining, materials and metallurgy, oil, gas and petroleum industries, pipeline, marine and offshore sectors) are encouraged to submit their original, unpublished contributions.
