@HTURKAK: It is a steel post for a noise barrier, subjected aerodynamic loads. Do you know if "normal" corrosion is worse compared to rust pitting?

I have also looked in DNV. Is rust pitting and 120 years corrosion the same? The DNV describe a SN curve for free corrosion in saltwater, maybe that should be used even through the steel section is subjected to corrosion in soil and air?

Eurocode for fatigue states that it's only valid (stated detailed category) if the steel is protected by coating, stainless steel or weathering steel. Corrosion may result in notches. In DNV it is stated that rust putting reduces the detail category with 2 classes. Therefore, proper corrosion...

Do anyone have experience with fatigue verification of a steel (S355) section exposed to corrosion? Will the detail category decrease due to the corrosion. I can't find anything in Eurocode describing this subject?

The grade is 355

Which conditions are good / poor for welding stainless steel and weathering steel together? Furthermore, can cracks occur in weldings between stainless steel and weathering steel as they have different properties?

A classic steel-steel expansion joint, is that the roller joint or another joint type?

The figure is just a quick sketch. What do you mean with rollers inside the flanges?

The concrete panel (see figure) will move back and forth, and grind against the weathering column. How would you make that connection, so that abrasion of the steel column will not occur.

Why is it a bad idea to weld stainless steel on weathering steel? Would you instead weld another weathering steel plate on the main steel column, where the column has contact with another construction part going back and forth?

It is outdoor, a post for a noise barriere. Why would you not weld on weathering steel?

Where do you normally not use washers? In the top of bottom of the anchor? Furthermore, is there any standard/rule regarding length of the anchors?

To avoid abrasion, could it be an idea to weld a stainless steel plate on the weathering profile, where it has contact with other construction parts which moves back and forth?

I have a weathering steel column. 1) How to calculate corrosion after 120 years? Any standards to use?

I have a steel column welded on a base plate, size 500x400x30mm. Anchors are M48, which are preloaded. The steel column is connected to a concrete pile. 1) Which grout thickness should be used? 2) Dynamic/fatigue load occur in the connection (preloading anchors are used). Working life is 120...

I have a steel column connected to a concrete pile with preloaded anchors and grout. What is the best way for leveling the steel column before grouting. Using normal leveling nuts will not work as the preloading length shall correspond to the entire anchor length. I have heard something about...

Thanks a lot for all answers

What if shrinkage reinforcement doesn't exceed flexural reinforcement? In that case, can I "ignore" shrinkage reinforcement?

SLS = Serviceability limit state (term used in Eurocode). According to Eurocode you shall design flexural concrete members for stresses/cracks.

I have a concrete slab, which are restrained in both ends. When designing for cracks in SLS, do I have to consider stresses from shrinkage and stresses from static load separately. Or shall I add the stresses together?
