Abstract

THE PAPER COMPARES AND DISCUSSES DISPLACEMENT DUCTILITY RATIOS OF REINFORCED CONCRETE WALLS TYPICALLY USED IN ONE- AND TWO-STORY HOUSES. DUCTILITY RATIOS ARE INVESTIGATED BY ASSESSING RESPONSE MEASURED ON 39 WALLS TESTED UNDER SHAKING TABLE EXCITATIONS AND QUASI-STATIC REVERSED-CYCLIC LATERAL LOADS. VARIABLES STUDIED WERE THE HEIGHT-TO-LENGTH RATIO AND WALLS WITH OPENINGS, TYPE OF CONCRETE, WEB STEEL REINFORCEMENT RATIO AND TYPE OF WEB REINFORCEMENT. AN EQUATION TO ESTIMATE THE AVAILABLE DUCTILITY OF A PARTICULAR WALL IS PROPOSED. BASED ON STATISTICAL ANALYSIS OF DATA, VALUES OF DISPLACEMENT DUCTILITY CAPACITY FOR CODE-BASED SEISMIC DESIGN ARE RECOMMENDED. SAFETY FACTOR OF DUCTILITY VALUES REFLECTS THE BEHAVIOR AND FAILURE MODE OBSERVED IN WALLS. DISPLACEMENT DUCTILITY RATIOS CAN BE USED TO COMPUTE BOTH STRENGTH MODIFICATION AND DISPLACEMENT AMPLIFICATION FACTORS FOR CODE-BASED SEISMIC DESIGN OF REINFORCED CONCRETE WALLS FOR LOW-RISE HOUSING.
