Here μ is the coefficient of internal friction . The latter term is clearly chosen by analogy with sliding of a body on a surface, which to the first approximation is described by Amontons' law (2.7)τ=μσ′ In Fig. 2.8, we have drawn the Mohr–Coulomb criterion and Mohr's circle ...
where Ast is the area of two-legged stirrups with diameter φt, s is the uniform spacing of the shear reinforcement, φ are the angles between inclined link of the W-stirrups and axis perpendicular to the shear force. The thickness of slab fulfilled the requirements of (ACI code 9.5.3 ...
4. In this model, "hard contact" is used to define the normal behavior between two surfaces. The “penalty function method” was adopted, and the coefficient of friction was set to 0.4 to simulate tangential behavior [28]. The action mode of mutual contact between the stud and the UHPC ...
coefficient of 0.4 was taken in Caltrans (1994). Dowel bars of AD and the supporting girder interface were modeled as rigid links. Interfaces of each concrete element (precast AD, CIP, and girder) were also applied as rigid links. At the symmetric axis of AD, the nodes were tied to the...
The prestressed hollow-core slab (PHCS) is a precast concrete member that can maximize productivity and structural performance efficiency of concrete cross-section. For the PHCS members produced by extrusion method, however, it is difficult to provide th
The correlation coefficient between the predicted value and the experimental value is R2 = 0.98667, and RMSE = 7.38. This model can reliably predict the shear strength of UHPC beams and provide designers with a reference for the design of UHPC beams. Finally, after sensitivity ...
the atomic orbital basis set45. The Brillouin-zone was sampled using the Monkhorst-Pack grid of specialk-points46. The convergence tolerances of energy, the maximum force, and the maximum displacement were 1.0 × 10–5 Ha, 0.002 Ha Å−1, and 0.005 Å for, ...
The anchor diameter and strength and the frictional coefficient between anchors and the wall of the holes in timber have significantly influenced the shear performance of the proposed shear connectors. Introduction TCC structures have been extensively applied in the construction of new buildings and ...
However, the shear force and unbalanced moment between the slabs and columns often result in brittle punching failure in the slabs with inadequate detailing [1]. This failure manifests as slab failure in the zone where the concentrated load is applied or failure in the column due to shear ...
Sheeting joints are extensive fractures that typically develop parallel to natural slopes. Embryonic sheeting joints initially constitute channels for wate
