STUDI ANALITIK KEKAKUAN ELASTIS PADA METALLIC STEEL DAMPER BERBENTUK X DENGAN SISI LENGKUNG
ABSTRACT: Amount of energy
subjected to the structure during the earthquake damages the building. Since
the last 20 years, a new protection system has been developed to increase
safety and reduce the damage in the structure when earthquake occured, it known
as seismic device, equipped by active and passive control system. The most
practical and suitable method in reducing seismic response in the structure is
by using a passive control system. Passive control system based on the
procedure of installation consist of viscous damper, viscoelastic damper,
friction damper and yielding damper. Yielding Metallic Device is usually known
as Metallic Steel Damper. The shape of this device which is often used was
damper with X-shaped (ADAS) or V-Shaped (TADAS). Metallic Yielding Damper can
be classified into 2 types in restraining shear force from earthquake, those
are bending towards strong axis and weak axis. If the installation is towards
strong axis, damper will reduce energy of the earthquake through bending
mechanism and inelastic shearing. Analytical structure calculation in strong
axis for approximately elastic stiffness which will be used without doing an
experiment in the laboratory. To determine the elastic stiffness, deflection at
damper will be defined by using strain energy method. Both deflection
contributed by bending and shear deformation were considered in the analysis.
The result of the deflection by using analytical of strain energy method will
be compared with experimental results in the laboratory.
