![]() Due to these advantages, the precast concrete structures have received much attention in recent years. Hence, the precast concrete structures can have better concrete quality and help to reduce the cost of labor and increase speed of construction. Then, the sensitivity analysis of some controlling material properties and geometrical parameters is performed using the validated computational model to further understand the performance of such a composite structure in load carrying capacity and ductility of the connections to meet the rapid engineering applications of precast concrete structures.Ĭompared to the traditional cast-in-place concrete structures, the precast concrete structures are usually manufactured in a controlled environment, i.e., plants, and then are installed at the construction site through certain connections. To validate the proposed computational model and demonstrate the nonlinear response of the GSS connector, the pullout experimental test of two engineering specimens is carried out under monotonic tensile load, and a good agreement between the numerical and experimental test results is observed. ![]() In the present study, a three-dimensional nonlinear finite element model of a GSS connector is developed by considering the nonlinear material behavior of each component to fully investigate its mechanical performance under axial tension. However, the current design recommendations for such a composite connection system do not accurately account for its material nonlinearity behavior. Thank you for visiting our website!

We offer a superior selection of quality products as well as competitive pricing to help get your project completed and under budget. Our informative and experienced representatives are ready to assist you with any questions that you might have, regarding your fiber optic network. Have questions about what Fiber Distribution Box will work for your setup? They are now used in aerospace, industrial, marine, and even automotive commercial applications. These connectors, and their evolutionary derivatives, are often called Military Standard, MIL-STD, or MIL-SPEC connectors. The type "AN" (army-navy) series set the standard for modern military circular connectors. Department of Defense and were originally developed in the 1930s for severe aeronautical and tactical service applications. MIL-SPEC Fiber Connectors are used by the U.S. GBIC modules also require this connector type.įiber ST Connectors, also known as straight tip connectors utilize a bayonet-style coupling type, enabling a simple twist-on and twist-off installation. SC Fiber Connectors are push-pull connectors and their the most common choice for FTTH (fiber to the home) applications for datacom and telecom. The LC connector is considered by some to be the replacement for the SC connector. It also has a smaller ferrule, making it popular for high-density data applications. LC Connectors are a type of push and pull connector similar to the SC connector, only it has a locking tab. These high-precision ceramic ferrule multimode connectors guarantee a 0.1 dB typical/0.5 dB maximum insertion loss per connector pair for exceptional network performance. It offers best-in-class optical performance in a quick, easy field-termination solution. This popular fiber connector can be installed in about 45 seconds without consumables. All primary fiber types are compatible.Īnother popular fiber connector Fiber Savvy supplies are the Corning UniCam Fiber Connector. Our fiber connectors are manufactured of superior quality materials, delivering the reliability you can depend on. It is of particular importance to minimize these characteristics, especially for long-distance networking, as they can negatively impact performance. There are two negative characteristics of fiber connectors to be concerned with: attenuation and reflection. This eliminates the air gap at the point of connection so there is no signal loss. Most fiber connector types are spring-loaded so the fiber faces are pressed together when the connectors are mated. We also supply MIL-SPEC Connectors for harsh rugged environments including military applications. The most popular versions include snap-in Lucent Connectors (LC connectors), push-on Square Connectors (SC connectors), and twist-on Straight Tip Connectors(ST connectors). The Best Fiber Connector Types for a Fiber Connectionįiber optic connectors are used to connect two runs of fiber optic cable and consist of an adapter assembly and two plugs.
