The stress-strain behavior of concrete can be improved by providing a lateral passive confining pressure, such as fiber-reinforced polymer (FRP) wrapping. Many axial models have been proposed for FRP-confined columns. However, few predict the confined columns with more than two specified cross-sections. A model cross-sectional unification was developed in this paper based on database from existing literature that includes circular, square, rectangular and elliptical are highly FRP jackets....
Abstract Most existing studies on fiber reinforced polymer (FRP) confined concrete have focused undamaged that is subjected to uniaxial monotonic compression. However, FRP jackets are usually applied columns with material damage and potential future damage. This paper investigates confinement before after jacketing. A total of 32 FRP‐confined specimens were tested under axial compression in this work. The prior jacketing was implemented as predamaging by applying preloading then release the...
This paper presents an experimental study on concrete cylinders confined by fiber-reinforced polymer (FRP) and loaded under constant axial load increasing bending moment. A total of 55 were tested with FRP thickness force ratio being the variables. Compared another path eccentricity load, response this loading scheme was very different. It is concluded that has a significant effect stress-strain behavior FRP-confined different models are required for paths. Based test results, model proposed...

There are many studies on fiber-reinforced polymer (FRP)-confined pre-damaged concrete under quasi-static strain rates. However, few have focused FRP-confined high Thus, an experimental and analytical investigation was conducted to obtain the mechanical behavior of different The results show that stress-strain curves, ultimate stress, values were affected by rate extent damage. A model considering developed modifying a loading. proposed evaluated using test data. evaluation can predict
Studying the stress-strain relationship of fiber-reinforced polymer (FRP)-confined rubber concrete (RuC) plays an important role in its application engineering projects. Most existing models are established based on test data FRP-confined with circular cross-sections, and effect section shape is not considered. Therefore, analysis-oriented model square columns was studied this paper for first time. A database that includes particle content peak stress-peak strain axial-lateral by collecting...
Abstract Fiber reinforced concrete beams are a popular research topic because of the improvement in performance with fibers. PVA‐FRC GFRP have better mechanical properties than those ordinary when considering combination multidirectional material properties. This article presents results an experimental study on flexural behavior beams. Seven were tested. The test variables included PVA fiber content and diameter. indicated that existence bars is effective for enhancing load‐carrying...
Lightweight aggregate concrete, known for its light weight, thermal insulation, and excellent durability, has garnered significant attention is considered an ideal material lightweight ultra-high-performance concrete. Previous research discovered that prewetting aggregates can continuously release water during the setting hardening process of providing internal curing. However, moisture behavior prewetted under different temperature humidity conditions, as well their curing mechanisms in low...
The compressive strength of fiber reinforced polymer(FRP) confined concrete is an important parameter in the design FRP strengthen structure. Most existing models FRP-confined column were obtained by regression analysis experimental data, and only few established based on theoretical derivation method. Therefore, it necessary to expand model, which derivation. In this paper, columns summarized evaluated with a large number published data. Then Griffith failure criterion, unified model that...
Marine silt formation is a special kind of soil in coastal areas. In recent years, there are more and deep large foundations at Currently, The research marine foundation very few. dealing with this situation, grouting frequently used measure, also an effective method to ensure the security or excavation pit on surrounding environment minimize impact. Therefore, it necessary Specialized study, accumulates experience for further development.
The principal-agent model between employers and engineering supervisors is established, considering such factors as the scale of employers' investment, special character exogenous random variable its influence. And influence these on sensitiveness compensation performance under asymmetric information analyzed. Based result, to be considered while establishing incentive system are put forward.
This paper focuses on the initial value problem for two-dimensional magnetic Bénard system with partial dissipation and zero diffusivity.Based energy estimates tricky analytical skills, we prove that always exist a unique global smooth solution without any smallness restriction data.
