Author(s):

V.V. Bertero and E.P. Popov

Publication:

Symposium Papers

Volume:

53

Abstract:

Results obtained from investigating the hysteretic behavior of flexural critical regions subjected to high and low shears, and of interior beam-column subassenblages of reinforced concrete ductile moment-resisting frames, are summarized and evaluated.

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.

Symposium Papers

Volume:

Abstract:

Slender sheer walls in multistory buildings are discussed in this paper and answers are given to such questions as "Why do we need them?" and "What do we know about their design?". Also discussed are the historical development of the use of shear walls, their performance in earthquakes of the past 10 years (both good and bad), and finally, the available design information and our future needs in the area of design of shear walls for strength, stiffness and ductility, as well as needs in the area of analysis for the dynamic response of shear wall structures.

Publication:

Symposium Papers

Volume:

53

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.
