I am designing a combined structure made of timber materials with different creeping parameters. How can I perform the serviceability limit state design according to EN 1995‑1‑1?
A high-rise steel structure has several stories and is stiffened by bracings in all stories.However, the first story is made of reinforced concrete. Therefore, the horizontal bracing should work via this concrete slab. How can I model this rigidly fixed concrete slab in RSTAB?
How does RF‑TENDON or RF‑TENDON Design consider the long-term losses due to creeping and shrinkage, relaxation of prestressing steel, and due to elastic deformation?
Where can I change the deformation coefficient kdef (EN 1995‑1‑1) or the creep coefficient φ (SIA 265) for long-term deformations in the case of automatic load combinations?
