Evaluation of prestress losses in concrete beams using destructive and non‐destructive methods

open access: yesStructural Concrete, EarlyView.
Abstract Over the past few decades, prestressing techniques have become essential in the construction of key structures, infrastructure, and bridges. The serviceability and safety of prestressed concrete (PC) elements are closely tied to the effectiveness of the prestressing process.

VHF adaptive antenna using a rear defogger [PDF]

open access: yes, 2012
This thesis presented the design of an adaptive bearnforming antenna using a rear defogger. The main purpose of this project is to develop the vehicular adaptive antenna for VHF band, which does not require the installation space, does not spoil the

The use of cement leftovers from the hollow of spun piles as an additive in self-compacting concrete [PDF]

open access: yes, 2018
Spun piles have been used widely by developing countries, including Malaysia, to construct the foundation of most construction projects. A spun pile is a reinforced precast and prestressed concrete that is compacted in a mould through spinning compaction.

Large‐scale tests of 50‐year‐old prestressed concrete bridge girders

open access: yesStructural Concrete, EarlyView.
Abstract An experimental investigation has been carried out as part of the BRIDGE|50 research project, focusing on large‐scale loading tests performed on five 50‐year‐old prestressed concrete (PC) girders. The study aimed at evaluating the structural response of five girders retrieved from a viaduct in the urban area of Turin, Italy, subjected to 4 ...

Flexural performance of concrete‐filled steel tubular beams with wood chip aggregate

open access: yesStructural Concrete, EarlyView.
Abstract This study investigates the flexural performance of concrete‐filled steel tubular (CFST) beams with partial replacement of aggregates by wood chips (0%–25%) through experimental and numerical analysis. This study is novel in that it experimentally and numerically investigates the flexural behavior of CFST beams with partial replacement of ...

Transfer Length of Strands in Prestressed Concrete Piles [PDF]

open access: yes, 2002
A top bar effect has been identified in prestressed concrete piles. The effect that this top bar effect has on the development of the prestressing strand is investigated. Strand transfer length is found to be proportional to the observed end slip.

Snap-through behaviour of a bistable structure based on viscoelastically generated prestress [PDF]

open access: yes, 2017
A novel form of shape-changing bistable structure has been successfully developed through the use of viscoelastically generated prestress. Bistability is achieved through pairs of deflecting viscoelastically prestressed polymeric matrix composite (VPPMC)

Pre‐failure behavior of continuous post‐tensioned and post‐grouted beam in case of tendon failure

open access: yesStructural Concrete, EarlyView.
Abstract Grouted tendons are a common solution for long‐span bridge structures. The grout provides bond and corrosion protection for prestressing steel. However, if the grouting is defective, corrosion of the prestressing steel may initiate and eventually lead to tendon failure.

Optimal structural design method for reinforced concrete column in buildings with high floor heights using a genetic algorithm

open access: yesStructural Concrete, EarlyView.
Abstract Globally, there is a growing trend toward taller, larger, and more structurally diverse buildings that require expansive interior spaces. Rapid technological advancements have surged the demand for data centers, while the expansion of e‐commerce has increased logistics volumes, driving the need for large‐scale warehouses.
