DESAIN STRUKTUR UTAMA CLEAR SPAN BAJA DENGAN VARIASI BENTANG DAN TINGGI KOLOM STRUKTUR

Abstract

This study aims to analyze and design the clear span steel structure with variations of structural span and
column height also to provide information on the weight increase of the structure in accordance with the increase of
structural span and column height, where the weight of the structure is closely related to the construction cost. The
structure is designed with four variations of column height that is 4m, 5m, 6m and 7m where each column height is
varied by 5 spans of structure is 15m, 20m, 25m, 30m and 35m. The design results show that the column and rafter cross
sections vary and increased according to changes in the structure span and column height. Magnification of structural
spans and height of columns result in greater structure weight so that the required cost will increase also in accordance
with the percentage of weight gain of the structure.
