A new meta-heuristic algorithm is proposed for optimal design of reinforced concrete (RC) frame structures subject to combinations of gravity and lateral static loads based on ACI 318-08 design code. In the present work, artificial bee colony algorithm (ABCA) is focused and an improved ABCA (IABCA) is proposed to achieve the optimization task. The total cost of the RC frames is minimized during...

The main aim of the present study is to achieve optimum design of reinforced concrete (RC) plane moment frames using bat algorithm (BA) which is a newly developed meta-heuristic optimization algorithm based on the echolocation behaviour of bats. The objective function is the total cost of the frame and the design constraints are checked during the optimization process based on ACI 318-08 code. ...

The numerical study has been conducted to investigate the behaviour of spun pile – cap connection based on common practice in Indonesia. piles manufactured Indonesia have low confinement where amount transverse reinforcement is less than 20% minimum requirement set by ACI 318-19. research objectives are parameters that affect connection. Three investigated are: details, effect concrete infill a...

This article presents the advantages and limitations of a recently developed Ultrasonic Guided Wave Leakage (UGWL) method in comparison to well-known Half-Cell Potential (HCP) their ability detect corrosion reinforced concrete (RC) bridge decks. research also establishes correlation between UGWL data chloride content RC slabs. Concrete slabs submerged 10% NaCl solution were monitored using both...
