Abstract:

Field-cast ultra-high performance concrete (UHPC) connections are an innovative and prospective solution for combining full-depth precast concrete decks and steel girders. However, previous studies show that the slip capacity of stud shear connectors embedded in UHPC cannot meet the requirements for ductile connectors by Eurocode 4, which can reduce the resistance of steel and concrete composite members. In this study, the rubber-sleeved stud shear connector, which is a composite of ordinary stud and rubber sleeve, was adopted for the field-cast UHPC connections. Push-out tests were conducted

Abstract:

Connectors are powerful architectural elements that allow the specification of interactions between software components. Since the connectors do not include behavior in UML, the components include the behavior for coordinating the components, complicating the designs of components and decreasing their reusability. In this study, we propose the enrichment of UML connectors with behavioral specifications. The goal is to provide separation of concerns for the components so that they are freed from coordination duties. The reusability of the components will increase as a result of such exogenous c

Glass fiber reinforced polymer (FRP) composite connectors used in precast sandwich insulation wall panels directly affect the safety of the wall. In practical applications, a precast concrete sandwich insulation wall panel is transported to the construction site for hoisting 3–5 days after steam curing, and its concrete strength typically reaches approximately 70% of the design strength (i.e., the concrete strength after natural curing for 14 days). This study investigated the natural curing of concrete for 14 days and analyzed the mechanical properties of FRP connectors with two different sec

Abstract:

Abstract - Headed stud shear connectors are commonly used to transfer longitudinal shear forces across the steel-concrete interface. In the areas of high shear, many studs should be welded to the top flanges to provide full shear connection in terms of strength. However, this causes long welding time, raise safety concerns, and also makes it difficult to remove a deteriorated concrete slab, which may damage. In this study, the static behaviour of Channelled, Tee, and Spiral shear connectors used in composite steel concrete beams was analytically examined using ANSYS. Ten specimens were modelle

Precast concrete sandwich panels consist of two outer layers connected by a central connector and an inner insulating layer that enhances thermal and acoustic performance. A key challenge with these panels is eliminating thermal bridges caused by metallic connectors, which reduce energy efficiency.

The second parameter involved two composite section types: steel I-section-concrete composite arch members (SICM) and steel plate-concrete composite arch members (SPCM). A total of eight samples were prepared in two groups. The first used the SICM and four connector types to get four samples: stud (SI), angle (AI), perfobond

Abstract:

Traditional stud and perfobond leiste (PBL) shear connectors are commonly used as load-transferring components in steel-concrete composite structures. Composite shear connectors fully utilize the advantages of traditional stud and PBL shear connectors. In order to maximize the advantages of composite shear connectors, a novel shear connector for complex environments was proposed. The steel-FRP composite bars (SFCBs) with excellent fatigue resistance and corrosion resistance were introduced to replace the steel bars. This study discussed the failure modes, load–slip curves, and load–strain curv

Abstract:

Recent research indicates that high-strength bolts could be more effectively and efficiently used to connect steel girders and fabricated decks or retrofit existing composite girders than headed studs. To reduce the number of bolt shear connectors and, thus, further accelerate the construction of composite girders, high-strength large bolts could be an excellent alternative, resulting in greater concrete stress below the bolt. Also, hybrid fiber-reinforced concrete (HFRC) has better tensile ductility and strength than that of ordinary concrete (OC). Therefore, this study tried to design eighte

Abstract:

A composite beam is a structural member that behaves as a single unit by using shear connectors between a concrete slab and an I-shaped steel girder. The composite ratio is crucial and is determined by the shear connectors’ ability to withstand the horizontal shear forces between the concrete and steel girder. In this study, a U-shaped composite beam was designed, which differs from conventional composite beams as it allows the use of a steel girder as a formwork. Moreover, angle-type shear connectors, instead of stud-type connectors, were employed. Based on this design, large-scale U-shaped c

In this research, woven waste tire stripes are proposed as an alternative material to wire mesh to make a gabion wall. The performance of the waste tire stripe-based gabion wall is highly dependent on the strength of its stripe, where the stripe connector plays an important role. This research aims to inspect the behavior of different stripe connectors for the gabion wall. To achieve this, a physical model was built and employed to test the strength of the gabion wall. Various stripe connectors are used; adhesive rubber glue, one inch nail, and two mm wire. The strength capacity of the models
