Shear Resistance Capacity of Traperzoidal Wab Shape With Opening |
| Abstract |
Generally, most high rise buildings are framed with steel structures and there are many problems due to the poor quality of this important structural welding, because its either field or factory welding can cause more uneconmical labor cost, more labor injuries, due to the stiffeners against web buckling.Only one fundamental way to remove non-nomogeneous poor quality and its structural failure is to get rid of the occurrences itself by reducing a scope of work at factory & field.This study shows how to substitute those stiffness for strain & stress capacity, displacements of beam with traperzoidal web section in other to find out the best design crieria.Test pieces are composed of web thickness 3.2 mm, upper and bottom flange THK 13mm, width of flange 150mm and depth of beam 300 mm. But there are three different shapes of web: a2=220, a1=110: a2=220, a1=220; a2=220, a1=110 diameter 100 mm web opening at one third of depth 300mm & half of depth 30 mm, |
