• 3D concrete printing and structural testing of nine reinforced beams. Aligned interlayer fibres steel cables as shear reinforcement. Full-field digital image correlation precise analysis crack kinematics. Development a mechanical model for reinforcement in printed (3DCP) offers many new possibilities. This technology could increase the productivity construction industry reduce its environment...

Masonry is one of the oldest materials that humans use for construction. It durable, as seen on ancient structures built thousands years ago, yet still in excellent shape. Recently, masonry walls have struggled to be competitive among other construction such precast concrete, tilt-up walls, timber, etc. This mainly due practices and lack a standardized modular system prevents offsite In this pa...

A bridge is a structure providing passage over an obstacle without closing the way beneath. The required passage may be for a road, a railway, pedestrians, a canal or a pipeline. Now a days, bridge deck section of Box shapes are used widely. Most of the bridges constructed are of Box girders. Method of post-tensioning in the construction of bridges is very common today. Most of the bridges are ...

A system-level shake-table test of a two-story low-damage concrete wall building was conducted in 2019. The consisted unbonded post-tensioned (UPT) walls with perimeter frames and different wall-to-floor connections to provide deformation compatibility. results highlighted that the measured lateral strength notably exceeded design value. This over-strength largely attributed compatibility defor...

The application of external post-tensioned steel bars as an effective way to strengthen an existing bridge has been so far used in many different countries. In recent decades, however, they have been replaced by bars made from Carbon Fiber Reinforced Polymer (CFRP), as a material with high tensile strength and corrosion resistance, to address several concerns with steel bars such as their appli...

Earthquake force, loading more than structural capacity, cracking, material fatigue and the other unpredicted events were undeniable in the structure life cycle in order that environmental conditions of the structure would be changed and treats health. Damage of structures such as crack, corrosion of the post tension cables from inappropriate grouting of the post tension structures and etc. can...
