Carbon Nanofiber Aggregate Sensors for Sustaining Resilience of Civil Infrastructures to Multi-Hazards by Mo YL in Crimson Publishers : Advancements in Civil Engineering & Technology Natural disasters (earthquakes, hurricanes, tornadoes. and floods) or man-made disasters or accidents (missile/aircraft impacts, fires. and explosions) lead to substantial damage on critical infrastructures and communities and have social, economic, and environmental consequences. As the safety of civil infrastructures is critically important, effective structural health monitoring (SHM) systems of infrastructures should be developed to avoid and mitigate the risks caused by various types of hazards. Carbon Nanofiber Aggregates (CNFAs) developed at the University of Houston are piezoelectric aggregates that can respond uniquely to different multi-hazards. This unique response makes this a sensor capable of being used in the Structural Health Monitoring (SHM) of civil infrastructures in each of th...

Evaluation and Strengthening of an Eight-Storey Existing Reinforced Concrete Building in Abha City, KSA by Mohammed Ismaeil in Crimson Publisher : Open Journal of Civil Engineering Saudi Arabia’s kingdom is not free from seismic tremors. It has encountered numerous quakes amid the ongoing history, and the past investigations on this field exhibited this contention. Many existing structures in Abha City have not been intended to oppose seismic forces. Moreover, it is imperative to contemplate the reaction of these structures under seismic conditions. Likewise, there is a lack in the examinations done in this field identified with Abha City. Consequently, existing structures ought to be assessed with respect to their ability for opposing expected seismic impacts before recovery works. Investigation was completed by utilizing auxiliary examination program (SAP2000) [1] with the utilization of static technique proposed by the Saudi Building Code (SBC) [2] to decide the reaction of regu...
