... of the effect of actions and R d is the design value of the ground resistance that depends on the ultimate limit state considered. The design value of effect of actions (E d ) is calculated from the characteristic values of effects of actions, affected by the partial factor on effect of actions (γ E ) whose...

... Engineers S.A., Athens, Greece ABSTRACT: An approach is proposed which permits to estimate rock mass properties as confident characteristic values, both local and average, according to Eurocodes. The approach aims currently to estimate the unconfined compression strength (UCS) of the rock mass based...
