Ultra-high performance concrete (UHPC) is a developing concrete and today is increasing to interest using it in structures due to its advantages such as high-compressive strength, modulus of elasticity, highly durability and low-permeability. Therefore, it is necessary to provide models for prediction of nonlinear behavior of this material. This study is aimed to investigate the tension-stiffen...

An assessment concerning the structural applicability and performance of fiber reinforced concrete (FRC) is presented for different bridge elements within a design framework. FRC as main bearing material in members has evolved from low-demand applications to increasingly ones, where bending shear are internal forces. In actual applications, this was reflected with initial slab-on-grade cases, t...

This study carried out comparative seismic performance of reinforced concrete frames infilled by masonry walls with different heights. Partial and fully infilled reinforced concrete frames were modeled for the research objectives and the analysis model for a bare reinforced concrete frame was also established for comparison. Non–linear static analyses for the studied frames were performed to in...

This paper presents a non-destructive test method for steel corrosion in reinforced concrete bridges by using a 3-dimensional digital micro-magnetic sensor to detect and analyze the self-magnetic field leakage from corroded reinforced concrete. The setup of the magnetic scanning device and the measurement mode of the micro-magnetic sensor are introduced. The numerical analysis model is also bui...

Nowadays, with the aging of bridges and advancements in technology, load testing has emerged as an effective method to assess existing concrete missing information, or where analytical methods do not provide accurate assessment. Two types tests are identified: diagnostic proof tests. Both rely on field measurements parameters structural responses bridge during test. A test measures response so ...
