Thermophysical and thermomechanical properties of basalt-phenolic FRP rebars under high temperature

Thomas Keller, Hongwei Zhu, Ting Li, Jiahui Shen

An experimental investigation was conducted on the thermophysical and thermomechanical properties of phenolic-basalt fiber-reinforced polymer (P-BFRP) rebars subjected to high temperature. As a comparison, vinylBFRP (V-BFRP) and epoxy-BFRP (E-BFRP) rebars ...

Static and Fatigue Biaxial Flexural Behavior of Strain-Hardening UHPFRC Thin Slab Elements

Xiujiang Shen

Cast-in-place thin layers of Ultra-High Performance Fiber Reinforced Cementitious Composites (UHPFRC) on the specific zones of existing reinforced concrete (RC) bridge decks has been demonstrated to be a technically efficient and economic rehabilitation an ...

EPFL2020

This paper addresses the uniaxial tensile response of Strain Hardening Ultra High-Performance Fiber Reinforced Concretes (SH-UHPFRC) subjected to very low strain rates and low temperatures. The influence of four different strain rates; 1 × 10−5, 1 × 10−7, ...

Biaxial flexural response of Strain-Hardening UHPFRC circular slab elements

Eugen Brühwiler, Xiujiang Shen, Wanghu Peng

The biaxial flexural response of strain-hardening UHPFRC circular slab element is investigated experimentally and analytically using the ring-on-ring test. The Digital Image Correlation (DIC) technology is applied to capture the 3D full-field of strain and ...

Performance assessment of through-tenon timber joints under tension loads

Yves Weinand, Aryan Rezaei Rad, Henry V. Burton

This paper aims to characterize the force-deformation response of through-tenon wood-wood connections subjected to tensile loads. Four beech LVL timber specimen groups with variations in the fiber orientation, and the tab insertion angle (45°, and 60°) are ...

2019

A multi-phase Ti-6Al-4V prepared by electron beam melting and thermal post treatments has been shown to exhibit increased strength and ductility over standard wrought or hot isostatic pressed Ti-6-Al-4V. The mechanical improvements are due to a prolonged, ...

Next generation synthetic fibers UHPFRC for sustainable structural applications

Amir Hajiesmaeili

The ever-increasing demand for rehabilitation of existing structures and construction of new ones, along with environmental issues of the construction sites represent a heavy burden for society in terms of economy and environment. Meanwhile, Ultra-High Per ...

EPFL2019

Representative and accurate characterization of the tensile behavior of strain hardening Ultra High Performance Fiber Reinforced Cementitious Composite (UHPFRC) remain a challenge. Currently, the uniaxial methods, like direct tensile test (DTT) and 4-point ...

2018

Strain Hardening Ultra High Performance Fibre Reinforced Concrete (SH-UHPFRC), has a high tensile strength (over 10 MPa) and exhibit significant strain hardening (several parts per thousand) under tensile loads. These appealing features make it a suitable ...
