This article deals with the determination of the concrete reinforcement for a beam stressed by tension only according to EN 1992-1-1. The aim is to show the tensile load of a member-type element (without imposed deformations) and to define the concrete reinforcement in accordance with the standard's construction rules and provisions using the RFEM structural analysis software.
RFEM and RSTAB provides two different methods for the superposition of load cases. Using load combinations, the loads of individual load cases are superimposed and calculated in a "big load case". On the other hand, result combinations only combine the results of the individual load cases. This article describes the with the basis of defining result combinations and explain it in detail on two examples.
In the H - Roofs category, imposed loads have to be applied. These are usually the technician loads for construction and maintenance. Since there is no maintenance for snow, category H must not include both snow and imposed loads together. You can consider thi in the options for automatic combinations.
The last part of my post deals with the consideration of forces resulting from the imposed deformation of a cross‑laminated timber plate when designing a structure with imposed loads.
