PENGARUH PENAMBAHAN SATU LANTAI TINGKAT TERHADAP KEAMANAN PORTAL GEDUNG BETON BERTULANG TIGA LANTAI
Abstract: The aim of this
research was to compare three and four floors of reinforce concrete portal
design, and the possibility of the
addition of one floor above the three floors building based on building safety.
Research was carried out by taking the example of two office building portals
constructed in the earthquake zone-one. Both portals were made from the same
sketch plan and designed in the full elastic system. The load combinations
(dead load, live load, and earthquake load) were subjected to both portals. The
loads complied with the Indonesian Code (Tatacara Perhitungan Struktur Beton
Untuk Bangunan Gedung, SNI 03-2847-2002). The dimension of portal structures
(beam, column, sloof, and foundations) and their reinforcements were properly
designed to carry the loads. Based on the dimension of portal and their
reinforcement obtained, a comparison could be made up of total reinforcing and
spacing of begel on both portals, and the possibility of the addition of one
floor above the three floors building. The results showed that the dimensions
of the structure (column, sloof, and foundation) of four floors portal were
bigger than three floors, had greater number of total longitudinal
reinforcement (include of beam), and the begel space of edge beam was more
tightly. Moreover, the addition of one floor above the three floors would be
dangerous for building safety and users.
