Turkey is located in a high seismicity region and has suffered extensive losses due to several major earthquakes that struck its various parts the past two decades. While are associated with damage loss wherever they may occur, destructive effects of those exacerbated by large volume code incompliant buildings constructed poor materials workmanship. As scale remedial initiative, recently embarked upon grand challenge retrofitting or renewing all high-risk within next 20 years. This...
Progressive deterioration and accumulated damage due to overloading, extreme events, fatigue necessitate the continuous monitoring of civil infrastructure ensure serviceability safety. With advances in sensor technology, data-driven structural health (SHM) strategies, particularly artificial neural networks (ANNs), have gained prominence for analyzing large datasets identifying complex patterns. Among these, autoencoders (AEs), a specialized class ANNs, are well-suited unsupervised learning...
Three service-learning projects of various content, workload, and community partnering were identified implemented in two core one elective undergraduate courses the Department Civil Environmental Engineering at University Massachusetts Lowell 2005. This paper presents how these service learning seamlessly integrated into existing without removing pertinent course materials a significant increase time commitment. Details on contents, structure, implemented, each project was used to address...
Ultra-high-performance concrete (UHPC) is a promising new class of material that likely to make significant contribution addressing the challenges associated with load capacity, durability, sustainability, economy, and environmental impact bridge infrastructures. This paper focuses on modeling UHPC design girders made UHPC. A two-phase model used for behavior was briefly discussed, implemented in preliminary case study. Based reported use applications, advantages, limitations, future...
ABSTRACT Thin‐film nanocomposite (TFN) membranes were fabricated by interfacial polymerization of a polyamide (PA) layer on the shell side hollow fiber membrane supports. TiO 2 nanoparticle loadings in thin‐film 0.01, 0.05, and 0.20 wt %. Nanoparticle‐free PA composite (TFC) served as comparative basis. The TFN characterized terms chemical composition, structure, surface properties separation layer. Incorporating nanoTiO improved permeability up to 12.6‐fold. During preliminary...
In this study, reinforced hollow fibre membranes were fabricated using different molecular weights of polyvinylidene prolidone (PVP Mw: 10, 40 and 360 kDa) take-up speeds (1, 2, 2.6 3.5 m/min). Prepared characterized in terms permeability; surface morphology hydrophilicity; pore size distribution; bovine serum albumin (BSA) rejection flux recovery ratio. Optimum permeability BSA obtained when PVP weight was kDa. After determination, advancing speed changed it seen that increasing ended up...
The focus of this paper is the implementation a backpropagation algorithm as potential solution for inverse source problem microwave imaging plain and reinforced concrete targets. data used in was obtained from numerical simulation far-field scattering by targets using typical frequency bandwidth commercially available radar systems. A finite difference-time domain (FD-TD) technique simulations. Electromagnetic (EM) properties various moisture conditions were previous study. total four...
This research investigated the changes in vibration characteristics of a simple reinforced concrete (RC) frame subjected to incremental cyclic pushover testing as basis for detection, quantification, and localization damage RC frames using data obtained before after seismic event. A half‐scale one‐story one‐bay plane was progressive through lateral loading incrementally increasing drift ratios. Ambient impact tests were performed at each increment ratio, modal analyses acceleration responses...
Rapid and reliable condition assessment of reinforced concrete structures in high seismicity regions is a priority task estimating their seismic safety. Non-destructive testing (NDT) methods may contribute to the practice by providing fast strength estimation while causing minimal or no damage structure. Drilling resistance an NDT method that has been used for mechanical characterization natural stone wood measuring force response constant penetration rate rotational speed. This paper...
Seismic retrofitting of reinforced concrete (RC) members using fiber polymer (FRP) composite materials has become a well-established technique for repairing and strengthening seismically deficient systems. Although there been significant progress on behavioral modeling FRP retrofitted RC as well implementation performance-based analysis design concepts, the studies investigating overall seismic behavior frames are still limited. This paper presents methodology retrofit provides an analytical...
There is an urgent need for rapid and reliable condition assessment of existing reinforced concrete (RC) buildings as a basis structural safety evaluation, especially in developing countries seismic regions such Turkey. Traditionally, RC structures are evaluated by taking core samples from limited number elements strength performing spot checks the steel reinforcement removing cover. In-situ determined through compression testing samples. Through checks, conformance with drawings realization...
