Relevant combinations of actions for the design of reinforced-concrete members in conventional buildings

Simplifying design –

Introduction

As a result of the introduction of the partial safety concept, the safety factors to be considered in the ultimate limit state design must be divided into the action Ed and the resistance Rd. Also, a distinction is made between permanent and variable actions for the purpose of determining the partial safety factors. Furthermore, the probability of the simultaneous occurrence of variable actions can be captured within potential combinations of actions (CoA) using so-called combination coefficients c0. A formal use of this new approach would lead to a large number of possible...
