ASCE-ASME Journal of Risk and Uncertainty in Engineering ’s Post

In this paper, the random field method (RFM) is used to represent the spatial variability of soil surrounding a pile, and the first-order reliability analysis method (FORM) is modified and employed to perform reliability analysis of a single pile. https://lnkd.in/gMk6thuR

🔥 🔥 🔥 New paper entitled 'Stability analysis and grouting treatment of inclined shaft lining structure in water-rich strata: a case study' has been published on Geohazard Mechanics with the following highlights: (1) The corrosion weakening mechanism of shaft lining in water-rich strata was revealed; (2) A three-level safety evaluation model for the instability risk of inclined shaft was constructed; (3) Intensive field measurement of surrounding rock water and damage environment in inclined shafts was carried out; (4) Comprehensive prevention and control measures are adopted for the water inrush source. https://lnkd.in/eK2eAg3u

Throw back to last summer (2023) when FPrimeC travelled to Taiwan to perform Non-Destructive Evaluation of a Concrete Mat Foundation at a Power Plant. The primary method used in this project was an adaptation on the Spectral Analysis of Surfaces Waves SASW method, where the propagation of stress waves are used to analyze the mechanical properties of concrete. The project brief for this investigation can be found below 👇 https://lnkd.in/gbM2RGmS

One of our early work and latest issued paper has been published in the Special Issue Failure Analysis of Marine Structure II for the Journal of Marine Science and Engineering. Contribution through this paper is in unifying the effect of corrosion-induced structural degradation on the ultimate strength of a high-tensile-steel (HTS) cargo ship using progressive collapse and nonlinear finite element methods. Uniform and pitting corrosion are modeled through selected scenarios, which hull elements might encounter during exploitation, producing a total of 148 calculation models. A work led by my professor Nikola Momčilović with the participation of other co-authors (Milan Kalajdzic, SPIRO IVOSEVIC, Ana Petrović). Check on link bellow.
