This paper reports the tests of multistorey frames including a base rotating wall under lateral load reversals. The wall base rotation limited the input forces and prevented damage in the wall. The beams, however, were forced to deform much during the wall rotation. The inelastic behaviour of frame members and the uplifting rotation of a structural wall at its base were idealised, and the effect of wall base rotation on frame behaviour was studied through inelastic earthquake response analysis. The base rotating shear walls performed better than or as good as flexural yielding walls.

Earthquake Response Analysis

A numerical algorithm is presented to analyze earthquake response of tall reinforced concrete (RC) chimneys based on stick multidegree-of-freedom models. The algorithm considers the eccentricity phenomena between spatial discrete nodes and corresponding centroids of investigated lumps. The spatial discrete segments of the chimney are used to construct the investigated lumps. The equations of dynamic equilibrium of the investigated lumps are derived, and the numerical calculation procedure is implemented. Phenomena of eccentricity are studied for 150 m and 210 m RC chimneys. Seismic stresses and effects of vertical ground motion for the two chimneys are also studied. Numerical results show that the tensile and compressive stresses of the seismic control cross sections of the chimneys may increase under the actions of several specific earthquake waves by considering existing eccentricities. The effect of eccentricity on the earthquake responses of tall RC chimney should be considered, and stresses caused by vertical ground motion should not be neglected to obtain accurate earthquake response of chimneys.
