This paper presents an experimental study on the monotonic and fatigue behavior of a link slab designed for a durable concrete bridge deck system. The requirements on the link slab in terms of material properties, dimensions, and reinforcement detailing are considered. Special focus is placed on the deflection capacity of the link slab and its fatigue performance. This paper discusses the choic...

Link slabs designed for macroscopically crack free concrete bridge decks system were experimentally tested. The property requirements of the link slab material were considered. Special focus was placed on the fatigue and durability performance. Introduction of a ductile Engineered Cementitious Composite (ECC) material is proposed for its ability to control crack width and to exhibit high ductil...

Sebagian besar jembatan di Indonesia yang menggunakan sistem perletakan sederhana, struktur antara lantai kendaraan atau plat slab jalan satu dengan lainnya selalu terpisah siar. Siar tersebut biasanya ditutup konstruksi dinamakan expantion joint berbahan besi baja. Permasalahan muncul adanya siar sering terjadinya ketidaknyamanan bagi pengguna karena terasa ketidak mulusan saat melintasi sebua...

Using boundary-integral projections for time-harmonic electromagnetic (EM) fields, and their numerical implementation, we analyze EM resonance in slabs of two-phase dielectric photonic crystal materials. We characterize resonant frequencies by a complex Floquet-Bloch dispersion relation ω = W (β) defined by the existence of a nontrivial nullspace of a pair of boundary-integral projections param...

Highway bridges are frequently constructed as simple span structures with steel or concrete girders and a cast-in-place concrete deck, spanning from one pier to another. At each end of the simple span deck, a joint is provided for deck movement due to temperature, shrinkage, and creep. Bridge deck joints are expensive and pose many problems with regard to bridge maintenance. Elimination of deck...

The subducted old and cold Pacific Plate beneath the young Philippine Sea Plate at the Izu-Bonin trench over the Cenozoic hosts regional deep earthquakes. We investigate slab morphology and stress regimes under different trench motion histories with mantle convection models. Viscosity, temperature, and deviatoric stress are inherently heterogeneous within the slab, which we link to the occurren...

This paper proposes a curved link-slab (CLS) structure, simplified into hingeless arch model, to address the current cracking phenomenon of CLS concrete. The stress formula under various loads is derived based on classical mechanic’s method. Based an actual bridge example, mechanical properties are analyzed different and load combinations. results show that: (1) significantly lower than that fl...
