KAJIAN KUAT GESER HORISONTAL CIRCULAR CASTELLATED STEEL BEAM WITH AND WITHOUT ADDING PLATES
ABSTRACT: In order to increase
the quality in building structure aspect, it needs to be observed some aspects,
like optimum aspect which include the using of the material as element of the structure building itself.
In the development, steel construction technology introduces Circular
Castellated Beam form that is steel beam profile with I-section which is
hollowed on the body in a circle opening form. The next development is for accommodate the opening for duct and
plumbing is developed into opening circular with adding plates. The unsuccessful structure which is happened on castellated
beam based on the previous research commonly happens on the body area between
two openings what is called by web-post. In this research, it is done theoretical
investigation and experimental testing to observe horizontal movement
phenomenon which is happened on web-post area. Test things which is used is
profile steel I 150x75x5x7 mm which
is modified into circular Castellated
Beam with and without adding plates with 5 openings. The testing consists of
bent load with 2 vertical point loads on cellular beam, and data which is used
based on Rosette Reading, the tense 45o which is set on web-post.
From the research result and the discussion found that horizontal movement tense
from experimental test result shows that adding plates on web-post show that
loading capacity and the horizontal shear strength is increased about 20 up to
30 percent.
