Relaxation method for pounding action between adjacent buildings at expansion joint

Abstract: SUMMARYThe paper under discussion presents a detailed study on the reduction of pounding force on buildings due to expansion joints being filled with rubber. From shake table experiments and numerical simulations, the authors of the paper concluded that the rubber can reduce the maximum pounding force and hence the pounding damage to buildings. However, the writers of this short communication observed some significant issues in the experimental results as well as the numerical simulations. These observations a… Show more

“…Numerical simulations are carried out for the same system with five force models in an attempt to confirm the results. The paper concludes ‘it is clarified both experimentally and numerically that structural damage due to pounding between adjacent buildings can be reduced by inserting a shock‐absorbing material between them’ .…”

“…The authors calculate the pounding force by two methods: (i) from the strains recorded ‘… at a location of 2 mm from the pounding surface …’ for both specimens (Eqn ) and (ii) from the absolute accelerations of the top floors of the frames (Eqn ). F=()εA+εB×E×A‘where ε Α and ε Β are the average values of the upper‐surface and lower‐surface strains at a location of 2 mm from the pounding surface for specimens F‐A and F‐B, respectively, E is Young's modulus, and A is the cross‐sectional area of the pounding surface’ .…”
