Theory of Structures If a concrete column 200 × 200 mm in cross-section is reinforced with four steel bars of 1200 mm² total cross-sectional area. Calculate the safe load for the column if permissible stress in concrete is 5 N/mm² and Es is 15 Ec 294 MN 264 MN 284 MN 274 MN 294 MN 264 MN 284 MN 274 MN ANSWER DOWNLOAD EXAMIANS APP
Theory of Structures A steel bar 20 mm in diameter simply-supported at its ends over a total span of 40 cm carries a load at its centre. If the maximum stress induced in the bar is limited to N/mm², the bending strain energy stored in the bar, is 511 N mm 611 N mm 411 N mm 711 N mm 511 N mm 611 N mm 411 N mm 711 N mm ANSWER DOWNLOAD EXAMIANS APP
