They indicate that using HPFRCC materials, instead of normal concrete in RC frames, increased the ultimate load, ultimate deflection, ductility ratio, and plastic hinge characteristics of frames.
The perceptive reference frame is introduced and the characteristics of perceptive frame are compared with time based reference frame.
To investigate (1) hysteretic damping effect of nonlinear connection stiffness and (2) the influence of input acceleration amplitude and vibration frequency on dynamic response characteristics of the frame, dynamic analyses for steel frame are performed by inputting sinusoidal acceleration waves at the basement.
The use of LBP-TOP features in the method by Guo et al. proves to capture the characteristics of each frame more effectively, and thus, the most appropriate pairs of frames are found to be stitched together.
The strain energy characteristics of the frame induced by the moving force are investigated as well.
The identification of modal characteristics of the frame (linear part) is based on an experimental investigation of its dynamic response.
Firstly, a parameter called as 'irregularity index' is proposed based on the dynamic characteristics of the frame to quantify the setback irregularity.
The geometric characteristics of the frame, the cross section dimensions and the reinforcement detailing of the columns and beam are presented in Fig. 7.
A prototype three-story steel dual-core self-centering braced frame (DC-SCBF) was designed, and its full-scale first-story one-bay DC-SCBF was tested to (1) validate the system response, (2) study force distributions in framing members as damage progresses in the DC-SCB, beam or columns, and (3) investigate the repair and replacement characteristics of the frame.
In this paper, the isolation effect of a 15-story medium-rise RC building in terms of the vibration period ratio (difference in stiffness values) between a superstructure and an isolation layer and and the diverse characteristics of a frame was analyzed.
