Document: 

SP53-18

Date: 

January 1, 1977

Author(s):

H. Gallegos and R. Rios

Publication:

Symposium Papers

Volume:

53

Abstract:

This paper analyzes the authors' experience in repairing reinforced concrete buildings damaged by earthquakes. Buildings damaged by a first earthquake were repairedd and subsequently, those repaired buildings underwent the effects of second and third quakes. In some cases, those new seismic actions caused further damage which also had to be repaired.

Publication:

Symposium Papers

Volume:

Abstract:

The importance of overturning forces and biaxial repsonse is studied for 3D reinforced concrete frame structures subjected to biaxial inputs. A biaxial yield rule is used for the moment-curvature relation.

Symposium Papers

Volume:

Abstract:

A mathematical model is developed for predicting the relationship between the axial force on an anchored reinforcing bar and the displacement of the loaded end of that bar relative to the surrounding concrete. The model has different forms for monotonic and reversed cyclic loading.

Symposium Papers

Volume:

Abstract:

High intensity cyclic loading tests are reported for 13 stub cantilever specimens. Bond conditions for the tensile reinforcement in those specimens were presumed to simulate conditions for beam bars in beam-column connections. A displacement controlled loading device was used.

SP53-04

Date: 

January 1, 1977

Author(s):

M. Yamada and H. Kawamura

Symposium Papers

Volume:

53

Abstract:

It is proposed that the aseismic capacity of a reinforced concrete structures is the steady state resonance capacity for an idealized one mass model of that structure subjected to a sinusoidal forced vibration.
