Tiivistelmä
The objective of the research was to determine the influence of additional steel elements to the bending stiffness of a steel member at the erection stage. Also the aim of the study was to consider different designs of downstands welding on a steel member.
The data for this thesis were collected from Finnish norm and regulations, technical manual for Deltabeam® design taken from the Internet and by interviewing structure engineers at Peikko Finland Oy.
The results of the study show that the influence of downstands to bending stiffness of steel member is neglectfully small. Consequently, there is no necessity to include them in the calculations which help to simplify the estimation.
According to the results a future study of downstands regarding to bending stiffness of steel cross-section is not required.
