Performance of Recycled Brick Aggregate Concrete Reinforced With Hybrid Rubber and Polypropylene Fibers Under Mechanical, Impact, and Elevated‐Temperature Loading

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Recycled brick aggregate (RBA) offers a practical route to reduce natural aggregate consumption, but its impact and elevated‐temperature performance remain unclear when combined with hybrid fibers. This study evaluates whether rubber fiber (RF) and polypropylene fiber (PPF) can improve the impact resistance (IR) and residual compressive strength (CS ...

Data Driven Based Bridge Damage Identification Using a Statistical Approach Utilizing Vehicle‐Induced Acceleration Responses

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
The integration of data‐driven methodologies in bridge health monitoring is gaining increasing attention due to their ability to overcome conventional approaches’ limitations. This study proposes a bridge damage identification method for simply supported bridges, leveraging output‐only vehicle‐induced vibration responses, eliminating the need for ...

Comparing the optimization of prestressed concrete bridge deck according to the AASHTO LRFD and AASHTO standard procedures using Cuckoo algorithm.

مجله مدل سازی در مهندسی, 2018
The high cost and time of implementation of the bridgeworks necessitate the optimization in the structural design. The optimization can extensively reduce the used steel, reinforcement, concrete and the time of doing project. In this study the effect of design elements in optimization of a bridge have been investigated.
