Whereas virtually any difference was determined between the compressive strength of specimens with slenderness 1.0 and the compressive strength of specimens with slenderness 2.0 on average in case of UHPC without fibers, the influence of slenderness gains in importance in case of UHPFRC with increasing fiber volume fraction. The broken lines, connecting the data points, illustrate this trend in

20.2.7 Compressive Behaviour DIANA FEA

20.2.7 Compressive Behaviour Concrete subjected to compressive stresses shows a pressure-dependent behaviour, i.e., the strength and ductility increase with increasing isotropic stress. Due to the lateral confinement, the compressive stress-strain relation is modified to incorporate the effects of the increased isotropic stress. Furthermore, it is assumed that the compressive behaviour is influenced

Effect of High-Intensity Strength Training on Knee Pain

Conclusions and relevance: Among patients with knee osteoarthritis, high-intensity strength training compared with low-intensity strength training or an attention control did not significantly reduce knee pain or knee joint compressive forces at 18 months. The findings do not support the use of high-intensity strength training over low-intensity strength training or an attention control in adults with knee
