Hi WARose, thank you very much for response. The vibrations are caused by some faults in generator and they are planned for repair in few months. We just want to make sure that with these vibrations structure integrity is not compromised. Would you please mind sharing graph you have? If not...
Hi,
Thanks for your all responses, to make things clear to understand I let you know that it is existing generator (very heavy machine) on first floor of a building which is supported by concrete slab and columns. Vibration is measured in all direction of bearings. Last year vibration amplitude...
Hi All,
I work in industry as a civil engineer and recently came across a problem. Actually mechanical engineer asked me regarding safety of footing for generator with 1500 cpm frequency and vibration amplitude which is increased to 4.1mm/sec. If I look into plot by Richard el (1962) it is way...
Hi SlideruleEra, thanks for your post, did you mean that I should provide new anchor plate with bolts and weld anchor plate with existing column? and encapsulate previous with concrete.
Hi, I am working in the manufacturing industry as civil engineer and while inspecting the structure for any integrity issues, i come across very often major steel columns with totally corroded nuts on anchor bolts. It is very hard to replace the columns, as it is expensive and would be major...
