Abstract
Geotechnical Evaluation of an Existing Tank Structure Located in a Seismic Zone This study presents the geotechnical evaluation of an existing tank structure under earthquake loads, based on TBDY 2018, international standards, and the published models in the literature. Due to the presence of liquefaction potential and clay layers thicker than 35 m with low shear strength in the field, non-linear site-specific analyses were performed Deprem in the time domain with and without pore pressure models. Soil softening and liquefaction act as a natural isolator, damping surface accelerations significantly, but they have caused high lateral displacements (2.0-2.3 m) and vertical settlements (58-128 cm) in the free field. It is estimated that the differential settlement at the tank structure is approximately 70-80 cm at the maximum and 5-10 cm at the lowest that is needed to be considered in pipe connections with the tank at the site. Under the additional earthquake loads from the superstructure, the bearing capacity and sliding control on the bottom of the tank structure and under the fill reinforced with geogrid were found to be safe.
期刊介绍:
The scope of Teknik Dergi is naturally confined with the subjects falling in the area of civil engineering. However, the area of civil engineering has recently been significantly enlarged, even the definition of civil engineering has somewhat changed.
Half a century ago, engineering was simply defined as “the art of using and converting the natural resources for the benefit of the mankind”. Today, the same objective is expected to be realised (i) by complying with the desire and expectations of the people concerned and (ii) without wasting the resources and within the sustainability principles. This change has required an interaction between engineering and social and administrative sciences. Some subjects at the borderline between civil engineering and social and administrative sciences have consequently been included in the area of civil engineering.
Teknik Dergi defines its scope in line with this understanding. However, it requires the papers falling in the borderline to have a significant component of civil engineering.
