Influence of Thermal Actions on the Effectiveness of Prestressing in Cylindrical Water Tanks

Applied Sciences
The paper presents the findings of an analysis of a tank subjected to thermal effects caused by variations in air and liquid temperatures. The structural analysis focuses on the influence that thermal actions exert on the distribution of prestressing ...

The Branch of Theoretical Analysis and Application Research on Grid String Structure

MATEC Web of Conferences, 2016
According to the ideas of the beam string structure, to stress structure is put forward, this is a very flexible cable for joined the rigid grid and support. This is the grid string branch structure. String branch established grid computing model. Static

Rotation capacity of continuous reinforced concrete slab strips revisited

Structural Concrete, EarlyView.
Abstract Rotation capacity is a key characteristic of statically indeterminate reinforced concrete structures, as it (i) enables bending moment redistributions, whether intentionally introduced through optimized reinforcement layouts or arising from unforeseen self‐equilibrated stress states, and (ii) promotes large rotations at failure load, thereby ...

The challenges of GFRP RC beam design for limit states

Structural Concrete, EarlyView.
Abstract Glass fiber reinforced polymer (GFRP) bars are used ever more frequently in concrete construction due to their non‐corrosive and anti‐magnetic properties. Their research over the past decades focused on fundamental questions, such as the design aspects of beams under flexural loads.

The Influence of High-Strength Bolts Stiffening on Flange Connection Behaviour

Engineering Transactions, 2019
Flange connections can commonly be seen in advertising board structures, which are subjected to wind loading. Depending on the structure’s geometry, additional torsion forces should be taken into account.

Probabilistic estimation of reliable sensor spacing for wire break detection in prestressed concrete using acoustic emission technique

Structural Concrete, EarlyView.
Abstract The acoustic emission (AE) technique has proven to be an effective method for detecting individual wire breaks in prestressed concrete structures affected by stress corrosion cracking (SCC). However, despite its widespread application, the quantitative assessment of AE monitoring reliability and optimal sensor placement remains unresolved ...

Steel beams strengthened with prestressed CFRP laminate: is there a need for laminate prestressing?

Electronic Journal of Structural Engineering, 2016
Strengthening structural members using Carbon Fiber Reinforced Polymer (CFRP) laminate is an effective method to increase their strength. Prestressing the CRFP laminate prior to attaching them to a steel beam can delay the common premature debonding ...

Experimental Evaluation of Prestress Force in Tendons for Prestressed Concrete Girders using Sensors

Journal of the Computational Structural Engineering Institute of Korea, 2015
The prestressing force has not been managed after construction nevertheless it is one of the importrant factors that maintain the structural safety of PSC girder bridges. The prestressing force is just measured during construction using jacking device and after that, it can not be managed practically.

Identification of invisible damage in prestressed concrete bridges—A demonstrator case using coda wave interferometry

Structural Concrete, EarlyView.
Abstract During their life cycle, prestressed concrete bridges are prone to wire breaks of their tendons due to fatigue or stress corrosion cracking. However, not all structures show visible cracking on the surface, which would provide timely warning of otherwise invisible damage. Brittle failure may occur.
