“…The results of a number of previous experimental investigations indicate that high joint shear stress demand can result in significant joint damage, loss of joint stiffness and loss of joint strength prior to flexural yielding of the beams that frame into the joint (i.e. joint failure) [3][4][5][6][7][8][9][10][11][12][13].…”

“…The results of previous research suggest also that, in addition to material properties and geometric configuration, a number of different design parameters may affect joint response. These design parameters include joint shear stress demand [3][4][5][6][7][8][9][10][11][12][13], joint transverse reinforcement ratio [3,6,[14][15][16][17], bond stress demand for beam longitudinal reinforcement passing through the joint [3,7,[18][19][20][21][22][23], and column axial load [7,9,14,17,[24][25][26][27][28][29]. For joints with sufficient strength to develop the yield strength of the beams framing into the joint, experimental data indicate also that drift history affects strength deterioration of the joint [30,31].…”

“…The developed models indicate that concrete compressive strength, in-plane geometry, out-of-plane geometry, joint eccentricity, beam reinforcement and joint transverse reinforcement are more important than other parameters in determining RC joint shear capacity. In this section, the individual influence of key parameters on RC joint shear stress plotted against joint shear strain at the peak is discussed by use of the joint shear strength and deformation models presented in equations (9) and (16).…”

An extensive experimental database (341 cases in total) has been constructed for reinforced concrete (RC) beamcolumn connections subjected to quasi-static cyclic lateral loading. All cases within the database experienced joint shear failure, either in conjunction with or without yielding of beam reinforcement. RC joint shear strength models, which are applicable to both modern and older types of beam-column connections, have been developed using the constructed database in conjunction with a Bayesian parameter estimation method. Following this same procedure established to develop the strength models, joint shear deformation models (at maximum joint shear stress) have also been developed. The proposed quantitative RC joint shear strength and deformation models indicate that the following parameters are most important towards determining joint shear strength and deformation capacityconcrete compressive strength, beam reinforcement, joint transverse reinforcement, in-plane geometry, out-of-plane geometry and joint eccentricity. Finally, the influence of these six key parameters on the RC joint shear stress against joint shear strain behaviour at peak response has been assessed.

A 10‐story reinforced‐concrete (RC) building was subjected to a shaking table test using E‐Defense, the largest three‐dimensional earthquake simulator in the world, to estimate the effects of a flexible foundation and seismic response of a mid‐rise building. Two structural systems with different base supporting conditions were adopted for two phases of tests for comparative purposes: the first system was free‐standing with base sliding and uplifting, and the second was a conventional RC seismic resisting system with a fixed base. This paper mainly reports the test results for the conventional RC seismic resisting system with a fixed base, which comprises a moment‐resisting frame system in the longitudinal direction and a frame system with multistory shear walls in the transverse direction. The objective of this research was to confirm the seismic capacity of a mid‐rise building designed in accordance with current Japanese building standards and guidelines. Even though the story drift ratio exceeded 3% under extreme motion exceeding the design earthquake, the structure remained stable throughout the tests, satisfying the design concept of collapse prevention performance, whereas relatively severe damage was observed in the beam–column joints. Crack observations indicated massive damage sustained by the beam–column joints. The measured shear deformations at the beam–column joints accounted for more than half of the inter‐story drift at the peak response.
