TBM pressure models: calculation tools [PDF]

open access: yes, 2015
Mechanized tunnel construction in soft ground has evolved significantly over the last 20 years, especially on the matter of settlement control. This was achieved by guiding the TBM operation to control the main factors that induce soil displacements ...

Optimization of Single-Layer Braced Domes

open access: yesTransactions of the VŠB: Technical University of Ostrava, Civil Engineering Series, 2017
The paper deals with discussion of optimization problem in civil engineering structural space design. Minimization of mass should satisfy the limit state capacity and serviceability conditions.

Limiting Distribution of the Three-State Semi-Markov Model of Technical State Transitions of Ship Power Plant Machines and its Applicability in Operational Decision-Making

open access: yesPolish Maritime Research, 2020
The article presents the three-state semi-Markov model of the process {W(t): t ≥ 0} of state transitions of a ship power plant machine, with the following interpretation of these states: s1 – state of full serviceability, s2 – state of partial ...

Vulnerability assessment of the S. João de Loure Bridge: Vouga’s river [PDF]

open access: yes, 2005
Steel bridges are particularly sensible to corrosion, which can put at risk the structural safety by affecting the joint elements. Having this in mind, the objective of this work was to evaluate the influence of the joint's stiffness in the structural ...

Reliability-based analysis of recycled aggregate concrete under carbonation [PDF]

open access: yes, 2018
Durability represents a crucial issue for evaluating safety and serviceability of reinforced concrete structures. Many studies have already focused on carbonation-induced corrosion of natural aggregate concrete (NAC) structures, leading to several ...

Serviceability limit state design of deep foundations

open access: yesGéotechnique, 2014
Although the settlement of deep foundations (piles) is not generally a concern if the piles are driven to refusal, settlement can become a design issue if no stiff substratum is encountered. This paper investigates the reliability-based design factors required for the serviceability limit state design of deep foundations.
