Steel tension element capacity Calculator: Calculates capacity of a steel tension element based on yielding of gross area or rupture of effective net area. Wood tension element capacity Calculator: Calculates capacity of a wood tension element based on allowable tension on net area (reduced by bolt holes) and, if desired, row and group tear-out. Seismic and Wind Force Calculator: Calculates and compares the wind and seismic story forces on a building, after entering general data (city, importance factor), seismic data (site class, seismic force resisting system), and wind data (exposure category, plan and parapet dimensions, and coefficients for directionality and topography).Įlongation due to axial load Calculator: Calculates elongation (as well as stress and strain) for prismatic elements subject to axial force. Wind Pressure Calculator: Calculates the wind pressure (psf) on the windward and leeward faces of rectangular buildings with flat roofs, after entering values for wind speed, exposure, roof height, importance, plan dimensions, directionality factor, and topography factor.
A newer version calculates governing loads based on distributed floor loads (psf), tributary areas, and number of floors. Governing load Calculator: Calculates governing load combinations for allowable stress design or strength design (LRFD). Snow load Calculator: Calculates snow loads based on slope, surface characteristics, and other parameters. Live and dead load Calculator: Calculates live and dead loads for girders, beams, and columns.
