The Nonlinear Response Emulation Analysis of the Stochastic Structure Subjected to the Earthquake Excitation
نویسندگان
چکیده
The earthquake response of the stochastic structures are analysed and studied by means of the emulation technology in this paper. A kind of non-linear emulation analysis algorithm of the stochastic structure is suggested. Also, a new kind of duplicate stochastic simulation concept is put forward. On this basis, combining the delamination sampling method, two examples of the RC structure are used to demonstrate the application and validity of the proposed emulation algorithm.

Stochastic analysis of two adjacent structures subjected to structural pounding under earthquake excitation
Seismic pounding occurs as a result of lateral vibration and insufficient separation distance between two adjacent structures during earthquake excitation. This research aims to evaluate the stochastic behavior of adjacent structures with equal heights under earthquake-induced pounding. For this purpose, many stochastic analyses through comprehensive numerical simulations are carried out. About...

Successful application of the algorithm requires judicious placement of the closed-loop eigenvalues from ...
متن کاملEffect of the frequency content of earthquake excitation on damage detection in steel frames
In this study, the effect of earthquake frequency content and noise effects on damage detection has been investigated. For this purpose, the damage was defined as nonlinear behavior of beams and columns, and several ground motion records were scaled so that some elements yield under the applied excitation. Then the acceleration response data of each floor obtained using the nonlinear dynamic an...

In this research, optimal design and assessment of multiple tuned mass dampers (MTMDs) capability in mitigating the damage of nonlinear steel structures subjected to earthquake excitation has been studied. Optimal parameters of TMDs on nonlinear multi-degree-of-freedom (MDOF) structures have been determined based on minimizing the maximum relative displacement (drift) of structure where for sol...
متن کاملA Phenomenological Study on Inelastic Torsion Caused By Nonlinear Behavior Changes during Earthquake Excitations
Torsion of many symmetric structures, which were designed based on the seismic codes, is due to their asymmetricity induced during inelastic behavior. Although the structure was designed symmetrically assuming elastic based criteria, different factors such as material inconsistency in structure, construction details discrepancy and construction errors may result in asymmetric behavior in inelas...
