A
Properties of Structural Steel Sections The structural designer has choice of a variety of sections, which are available in the market. This appendix provides properties of structural steel sections often used in practice. For more complete details of I-sections, channels, equal and unequal angles, and T-sections refer to IS: 808-1989. Note that IS: 808 does not give values of the plastic section modulus. Hence these values for I-sections and channels have been provided based on IS: 800. Note that there are some small differences in the values given by IS: 808 and IS: 800. Only the values given by IS: 808 have been used in this book. However, these differences in values will not affect the design much. Also included in this appendix are the wide flange sections, which have been introduced recently (more information on these sections may be obtained from M/s. Jindal Vijayanagar Steel Limited). Properties of some castellated beams (I-section and channels) have also been included. Properties of circular tubes (IS: 1161-1998), square and rectangular hollow sections (IS: 4923-1997 and Tata steel catalog), and cold-formed lipped channel and zed sections (IS: 811-1987) are also included in this appendix. More details about these sections may be found in the respective Indian Standard.
Indian Standard Rolled Steel Plates Steel plates are available in the following widths and thicknesses. Widths: 160, 180, 200, 220, 250, 280, 320, 355, 400, 450, 500, 560, 630, 710, 800, 900, 1000, 1100, 1250, 1400, 1600, 1800, 2000, 2200, and 2500 Thickness: 5.0, 5.5, 6.0, 7.0, 8, 9, 10, 11, 12, 14, 16, 18, 20, 22, 25, 28, 32, 36, 40, 45, 50, 56, 63, 71, and 80

A
Properties of Structural Steel Sections The structural designer has choice of a variety of sections, which are available in the market. This appendix provides properties of structural steel sections often used in practice. For more complete details of I-sections, channels, equal and unequal angles, and T-sections refer to IS: 808-1989. Note that IS: 808 does not give values of the plastic section modulus. Hence these values for I-sections and channels have been provided based on IS: 800. Note that there are some small differences in the values given by IS: 808 and IS: 800. Only the values given by IS: 808 have been used in this book. However, these differences in values will not affect the design much. Also included in this appendix are the wide flange sections, which have been introduced recently (more information on these sections may be obtained from M/s. Jindal Vijayanagar Steel Limited). Properties of some castellated beams (I-section and channels) have also been included. Properties of circular tubes (IS: 1161-1998), square and rectangular hollow sections (IS: 4923-1997 and Tata steel catalog), and cold-formed lipped channel and zed sections (IS: 811-1987) are also included in this appendix. More details about these sections may be found in the respective Indian Standard.
Indian Standard Rolled Steel Plates Steel plates are available in the following widths and thicknesses. Widths: 160, 180, 200, 220, 250, 280, 320, 355, 400, 450, 500, 560, 630, 710, 800, 900, 1000, 1100, 1250, 1400, 1600, 1800, 2000, 2200, and 2500 Thickness: 5.0, 5.5, 6.0, 7.0, 8, 9, 10, 11, 12, 14, 16, 18, 20, 22, 25, 28, 32, 36, 40, 45, 50, 56, 63, 71, and 80
