BEHAVIOR OF BEAM-COLUMN JOINTS WITH DIFFERENT BEAM-COLUMN CONCRETE STRENGTHS

Abstract
ABSTRACT
In high-rise buildings and heavy loaded structures where RC columns
are subjected to heavy loads, High Strength Concrete (HSC) used in column
construction is essential for the purpose of reducing column size and increasing
column capacity. However, from the economical standpoint, combination of
high and normal strength concrete (NSC) in building construction is becoming
common practice, where HSC is used for columns and NSC is used for the
surrounding beams/slabs floor system. This creates a situation where concrete
strength of the column portion at the beam/slab floor level is lower than
concrete strength used for rest of the column. Previous studies indicated that
such variation in concrete strength affects the load carrying capacity of the RC
columns.
