2- Problem:

A structure suspended by EN3 tie-bars is equivalent of 100,000 N. The tie-bars each have a diameter of 28 mm. If the SF is 10, calculate the minimum number of tie-bars

 

Given: Material EN3 W = 100,000 N d = 28 mm SF = 10   Required: n

Solution:

From Chart 9:

For steel EN3 σ_st = 460 N/mm²
