Analysis of history in time of systems with two degrees of freedom

Types of analysis :
• Elastic analysis of history at the time• Two types inelastic analysis of history at the
time

Types of excitation
• Load linear function• Load trilinear function• Load harmonic function• Record seismic acceleration

Important features
• Use OpenSees software • Analysis based on the Newmark method• The damping is established directly with
damping elements• Analysis inelastic uses two hysteretic bilinear
model (Bilinear 1 y Bilinear 2)

Applications :
• Study of the response to forced excitation• Study of the response to seismic excitation • Comparison between elastic and inelastic
response
