Abstract:
Here, to improve economy of traditional frame-eore tube (FCT) structure, a new frame-distributed core tube-core tube (FDCT) high-rise structure system was proposed to reduce the enclosed area of traditional tube body. Furthermore, a new frame-distributed rocking core tube-core tube (FDRCT) high-rise structure system was proposed to improve the aseisrnic capacity of FDCT due to stiffness-weakening. According to simplified analysis models of FCT structure, FDCT structure and FDRCT structure, dynamic equations of the 3 structures were established based on Lagrange equation. Through analyzing time history responses of the 3 structures under earthquake and relevant parametric analyses for mass of distributed rocking core tube, it was shown tliat FDRCT structure with additional nuking system has excellent energy dissipation and shock al (sorption performance. Dynamic time history analyses of the 3 structures under different site conditions and different types long-period seismic waves were performed, respectively. The results showed thai FDRCT structure has energy dissipation and shock absorption effects under action of different types seismic waves, and it is more superior under long-period seismic waves; performance-profit total values of the 3 structures are evaluated, data reveal FDRCT structure can not only improve the economy of structure under action of different types seismic waves, but also guarantee the safety of structure under earthquake. In order to improve the economy of traditional frame core lube (FCT) structural system, a new high-rise structural system of frame-distributed tube-core tube (FDCT) is proposed to reduce the enclosed area of traditional tube. Furthermore, the frame-distributed rocking tube-core tube (FDRCT) high-rise structural system is proposed to improve the reduced seismic capacity of FDCT due to the weakened stiffness. According to the simplified mechanical models of FCT, FDCT and FDRCT, the three structural dynamic equations are established based on Lagrange Equation. By analyzing the time history response of the structure subjected to earthquake and the effect of mass parameter of distributed rocking tube, it is proved that the FDRCT structure with rocking system has excellent energy dissipation and damping performance. The dynamic time history analysis of the three structures under different site conditions and different types of long-period earthquake waves is carried out, and the results show that the FDRCT structure could has energy dissipation and damping effect under different types of earthquake waves, and it is superior under long-period seismic waves. By evaluating the performance-profit value of the three structures, it show that the FDRCT structure can improve the structural economy and ensure the safety performance under different types of earthquake waves. © 2023 Chinese Vibration Engineering Society.
