CALCULATION TABLE FOR OBLIQUE ECCENTRIC COMPRESSION COLUMN BY INTERACTIVE CHART METHOD Part 1 - Methodological content

Civil Engineering

ABSTRACT Interactive diagrams have been widely used in countries around the world and have been included in design standards such as ACI-318, BS-8110. In Vietnam, recent studies have also mentioned the construction of interactive charts to design reinforced concrete columns. The article researches to set up an automatic calculation table to calculate reinforcement for rectangular columns subjected to oblique eccentric compression. The author team also built a calculation table to check the bearing capacity of columns by the interactive chart method. many calculation examples were also conducted to verify the proposed calculation table and compare it with the calculation theory and the existing reinforcement calculation program. The author organizes the implementation according to the five main contents consist of: Part 1-Methodological content; Part 2-Principles of building interactive charts according to current Vietnamese standards; Part 3- Method of calculating reinforcement area; Part 4-Simulate the system on specialized software; Part 5- Evaluate calculation results.
