| dc.description.abstract | Secondary beam is the non-primary structural elements in building that commonly applied
to structures that have long span frame. The principle of the secondary beam is to transfer the
structure load to the primary beam. Since the non-primary structural elements, the secondary beam
is designed with the purpose of structural efficiency rather than structural earthquake-resistant
capacity. Therefore, a comparison of the influence of several secondary beam configurations on the
structural response of the building is observed with principles of earthquake-resistant building in
this study. The results are expected to provide information regarding the influence of secondary
beams on the 7-story building that applies earthquake-resistant structure principles.
Structural members are designed with minimum height by considering structural member
span (SNI 2847-2019). Secondary beam configurations 1 to 5 are secondary beam configurations,
without secondary beam, on weak axis, strong axis, both weak and strong axes, and both diagonal
axes, respectively. Structure model variations with 5 secondary beam configurations are evaluated
by earthquake resistant building code (SNI 1726-2019). Structure response result of structure with
5 secondary beam configurations are compared to conclude secondary beam influence in structure.
The result of research shows that the configuration of secondary beam in the structure
influences the structure response. Structure with secondary beam tend to have lower structure
volume and more period (T) except secondary beam configuration 5. The structural response resulted
in deflection and P-delta increases for model variation 2 to 4 and deflection and P-delta decreases
for model variation 5 compared to model variation 1 as a control. | en_US |
