“…ANSYS is capable of modelling RC using SOLID65 element. The capability of SOLID65 element in simulating the nonlinear response characteristics of RC structures such as degradation of stiffness, lateral deformation and cracking of concrete has been verified in several research studies (Dahmani, Khennane, & Kacia, 2010;Vasudevan, Kothandaraman, & Azhagarsamy, 2013). ANSYS employs Willam and Warnke failure criterion (Willam & Warnke, 1975) for detecting the failure of RC elements.…”

A probabilistic method based on FEMA P695 is employed for validating the response modification factor of reinforced concrete pedestals in elevated water tanks. In the current codes and standards, the response modification factor of elevated water tanks is mainly based on engineering judgement. Ten models of elevated water tanks with different tank sizes and pedestal heights are selected for the investigation. Initially, the prototypes are designed based on the current codes and standards. Next, the finite element models of the prototypes are developed. By performing incremental dynamic analysis, the probability of collapse for each prototype is calculated under different seismic loading conditions and system uncertainties. The results of the study validate and confirm the current response modification factor values and show that the tank size has a significant effect on the nonlinear seismic response behaviour of elevated water tanks. In addition, it is revealed that heavy tank sizes that are designed in accordance with codes and guidelines are more vulnerable under seismic loading compared with light and medium tank sizes.

“…Therefore, these formulas serve as the guide for FOG error compensation in a thermal field, effectively paving the way for a rational error compensation plan. (Wang et al, 2013(Wang et al, , 2017. As the main borehole of this project, the SK-2 east borehole was designed to reach a depth of 6400 m, in order to penetrate the Cretaceous strata and reach the base of the basin.…”

The working environment in hot dry rock boreholes, encountered in deep geothermal investigation drilling and ultra-deep geological drilling (up to 5000 m), is very difficult at the present stage. We have developed a drilling trajectory measuring instrumentation (DTMI), which is based on the interference fiber-optic gyro (FOG). This can work continuously, for 4 h, in an environment where the ambient temperature does not exceed 270 • C and the pressure does not exceed 120 MPa. The DTMI is mainly divided into three parts: an external confining tube, a metal vacuum flask, and a FOG measurement probe. Here, we focus on the mechanical design, strength, and pressure field simulation analysis for the external tube, the structural design and temperature field simulation analysis for the vacuum flask, and the FOG Shupe error analysis and compensation in the temperature field. Finally, through the engineering applications of the SK-2 east borehole of the China Continental Scientific Drilling (CCSD) project and the geothermal well of Xingreguan-2, the data measurements of the drilling trajectory were used to analyze the stability of the DTMI. The instrument realizes long-duration, high-stability work in the process of making trajectory measurements in an ultra-deep hole. The instrument has the characteristic of anti-electromagnetic interference and enables work to be carried out in the blind zone of existing technologies and instrumentation. Therefore, DTMI has great potential in the promotion and development of geological drilling technology.

“…Local thickening of the ends of the joint thread is one common processes for improving the strength of the confining probe joint (Vasudevan et al, 2013). According to the work experience and the actual situation, the outer diameter of the probe tube is designed to be 73mm, and the inner diameter of the pipe body is selected as 68mm (GB), 67.5, 67, 66.…”
