Document Summary
If building will collapse: calculate factored live loads and dead loads. Dead load kpa (kn/m^2) x frame spacing. Live load goes in the middle if not given location as this causes maximum bending. Using effective length use pl/4 and wl^2/8 to find moments. Use unit loads and multiply at end by load at end (use factored loads or multiply by factor at this stage) Then calculate combination moments and resultant shear force on each support. Use max moment and max shear (usually at ends: check if moment capacity is satisfied (cid:1839) min (cid:4666) (cid:1839)(cid:3051), (cid:1839)(cid:3029)(cid:3051)(cid:4667, where =(cid:882). (cid:891) (cid:1864)(cid:3032) (mm) Get section properties for beam used (with typical values from 360ub50. 7) Ignore mb because fully restrained still need in question 3. Calculate the reference buckling moment, mo for the segment [equation 5. 6. 1. 1(3) of as4100] Le x 1. 4 need to explain better. Determine slenderness reduction factor, s for the segment [equation 5. 6. 1. 1(2) of as4100]
