Effect of Elevated Temperature and Internal Pressure due to Severe Accidents on the Internal Pressure Capacity of Prestressed Concrete Containment Vessel

open access: yesInternational Journal of Energy Research
The integrity of containment buildings in nuclear power plants is crucial for preventing the release of radioactive materials during severe accidents. This study investigates the effect of the uncertainty in temperature‐dependent strength of concrete on the internal pressure capacity of prestressed concrete containment vessel (PCCV).

Development of a High‐Sensitivity and Adjustable FBG Strain Sensor for Structural Monitoring

open access: yesStructural Control and Health Monitoring, Volume 2023, Issue 1, 2023., 2023
In this paper, a new fiber Bragg grating (FBG) strain sensor with adjustable sensitivity is invented. The sensitivity adjustment, strain sensing, and temperature compensation principles of the sensor and the corresponding formulae are developed. The prototype sensor specimen is developed, and a series of tests are performed to investigate its strain ...

Safety Risk Evaluation of Large and Complex Bridges during Construction Based on the Delphi‐Improved FAHP‐Factor Analysis Method

open access: yesAdvances in Civil Engineering, Volume 2022, Issue 1, 2022., 2022
With the increase in construction scale and difficulty of large and complex bridges in China, it has become increasingly difficult to assess the safety risks of bridges during the construction period. Therefore, how to reasonably assess the safety risk of large, complex bridges during construction has become particularly important.

Optimal Design Method for Vessel‐Bridge Collision Based on Life‐Cycle Theory

open access: yesAdvances in Materials Science and Engineering, Volume 2022, Issue 1, 2022., 2022
As structures crossing waterways, bridges are obstacles to vessels. Vessel‐bridge collisions are inevitable. They not only involve the safety of vessel passage but also seriously affect the safe operation of bridges. Vessel‐bridge collisions cause not only huge economic losses and casualties but also severe political and environmental losses.

Study on the Time‐dependent Reliability of Corroded Reinforced Concrete Bridge Structures due to Ship Impact

open access: yesAdvances in Civil Engineering, Volume 2022, Issue 1, 2022., 2022
The cumulative damage caused by chloride ion erosion to coastal bridge structures reduces the ship impact resistance of channel bridge structures and leads to changes in reliability of bridge structures on ship impact. It is of great theoretical and practical significance to study the performance degradation change law of corroded bridge structures and

Cytoskeletal prestress: The cellular hallmark in mechanobiology and mechanomedicine

open access: yesCytoskeleton, Volume 78, Issue 6, Page 249-276, June 2021., 2021
Abstract Increasing evidence demonstrates that mechanical forces, in addition to soluble molecules, impact cell and tissue functions in physiology and diseases. How living cells integrate mechanical signals to perform appropriate biological functions is an area of intense investigation.

Research on Bridge Structure Reliability Evaluation due to Vessels Collison Based on a Statistical Moment Method

open access: yesAdvances in Materials Science and Engineering, Volume 2021, Issue 1, 2021., 2021
Damage to bridge structures caused by vessel collision is a risk for bridges crossing water traffic routes. Therefore, safety around vessel collision of existing and planned bridges is one of the key technical problems that must be solved by engineering technicians and bridge managers.

Instrumentation of a prestressed concrete containment vessel model [PDF]

open access: yes, 1995
A series of static overpressurization tests of scale models of nuclear containment structures is being conducted by Sandia National Laboratories for the Nuclear Power Engineering Corporation of Japan and the U.S. Nuclear Regulatory Commission. At present, two tests are being planned: a test of a model of a steel containment vessel (SCV) that is ...
