NONLINEAR SIMULATION ANALYSIS OF TAPERED REINFORCED CONCRETE COLUMN (SOLID AND HOLLOW) BEHAVIOR UNDER AXIAL LOAD

Tapered columns are a type of column that is used for different purposes, including architectural purposes or structural needs to take into account the changes occur moments along with height column. For example, in highway bridges, tapered reduce number transmitted base and from there foundation. This research studied analysis short reinforced concrete variable cross-sections linear manner by using ANSYS V.15 software package. The variables were included section, solid hollow, ratio longitudinal transverse reinforcement, hollowness, comparison numerical results those obtained previous study.The we simulation models showed very good agreement experimental studies them. can also be observed through statistical arithmetic mean standard deviation when compared. Thus, proposed model hypotheses suitable formulating behavior these under effect axially applied load other variables. based on loads, load-displacement curves, crack patterns, failure modes. increasing reinforcement increases resistance R.C. ductility index decrease corresponding lateral displacement. changing section hollow solid. Finally cracks pattern represented crushing spalling out some parts at end diagonal places, especially tapered.
