Estimation of Shear Strength by using Cruciform Joints

Shear Strength of Rock Joints Based on Quantified Surface Description

One of the primary objectives of this work is to better understand the frictional behavior of joints under shear loads, including the creation of damage zones. Discontinuities have an important influence on the deformational behavior of rock systems. The choice of a general criterion to determine the shear strength of rough rock joints is a general problem that has been investigated for many ye...

Study on the shear strength degradation of ACA joints induced by different hygrothermal aging conditions

Article history: Received 13 June 2012 Received in revised form 1 June 2013 Accepted 15 June 2013 Available online 17 July 2013 The effect of the different hygrothermal conditions on the shear strength degradation of ACA joints and the difference among them are studied in this paper using experiments and numerical simulations. First of all, several hygrothermal aging tests with different accele...

Shear Strength of Unfilled and Rough Rock Joints in Sliding Stability Analyses of Concrete Dams

Strength of Composite Scarf Joints

In recent years, large composite structures have been used increasingly in the aerospace and naval industries. Such a large composite structure is mostly fabricated using the scarf joining technique so that multiple substructures can be connected together. Figure 1 shows three commonly used scarf joint configuration. Among the three, the step/overlap joint is considered as the strongest because...

Shear Strength of Scots Pine Wood and Glued Joints in a Cold Climate

The impact of cold temperatures on the shear strength of Scots pine (Pinus sylvestris) joints glued with seven commercially available adhesives was studied in this work. The cold temperatures investigated were: 20, −20, −30, −40, and −50 °C. Generally, within the temperature test range, the shear strength of Scots pine solid wood and wood joints were more resistant to the effect of temperature ...
