Appendix Dead and Live Loads International Building Code 2003 (IBC) 1607.1: According to IBC 2003, table 1607.1, the minimum uniformly distributed live loads and minimum concentrated live loads are as follow: Occupancy or Use Uniform (psf) Concentrated (lbs) Office building Office Lobbies and first-floor corridors Corridor above first floor 50 100 80 2000 2000 2000 1607.5 Partition Loads , in office building where partitions are subjected to change, provision for partition weight shall be made, whether or not partitions are shown on the construction documents, unless the specified live load exceeds 80 psf ( 3.83 KN/m2 ). Such partition load shall not be less than 20 psf ( 0.96 KN/m2 ) Superimposed Dead load : this type of load is based on engineering judgment. For Agricultural Hall and Annex, an assumption of 15 psf will be made for the superimposed dead load. BS8110 2.1: According to BS8110, Data Sheet 2, the imposed load on floors as follow: Occupancy or Use Uniform (KN/m2) Concentrated General Office 2.5 KN/m2 (52.2 psf) 2.7 KN ( 607 lbs) Partitions 9.1.3 : The weight of the partition should be included in the dead loads of the floors and it is convenient to consider such weights as equivalent uniformly distributed loads. For an office building, the minimum load is 1 KN/m2 or 20.5 lbs/ft2 . Superimposed Dead load : The same superimposed dead load will be assumed for the calculations ( 15 psf ) Load Combinations

ACI 318-02 9.2.1 The required strength U shall be at least equal to the effect of factored loads in equations (1-7). 1- U = 1.4(D+F) 2- U = 1.2(D+F+T) + 1.6 (L+H) + 0.5 (Lr or S or R) 3- U = 1.2D + 1.6(Lr or S or R) + (1.0l or 0.8W) 4- U = 1.2D + 1.6W + 1.0L +0.5(Lr or S or R) 5- U = 1.2D + 1.0E+ 1.0L + 0.2S 6- U = 0.9D +1 .6W + 1.6H 7- U = 0.9D + 1.0 E + 1.6 H Note: D = Dead loads, or related internal moments and forces E = Load effects of seismic forces, or related internal moments and forces F = Loads due to weight and pressure of fluids with well defined densities and controllable maximum height, or related internal moments and forces L = Live loads, or related internal moments and forces Lr = Roof live load, or related internal moments and forces R = Rain load or related internal moments and forces S = Snow load or related internal moments and forces T = Cumulative effect of temperature, creep, shrinkage, differential settlement, and shrinkage-compensating concrete. U = Required strength to resist factored loads or related internal moments and forces W = Wind load or related internal moments and forces BS8110 2.1 : Design Loads and strength, and partial safety factor (Data Sheet 1) Condition Dead + imposed load ( + earth pressure) 1.4 Gk + 1.6 Qk + 1.4 En Dead + wind load ( + earth pressure) 1.4 ( Gk + Wk + En) Design loads Dead + imposed + wind load (+ earth pressure) 1.2 ( Gk + Qk + Wk + En) Note: Gk = Characteristic dead load Qk = Characteristic imposed load En = Characteristic earth and/or water load (if applicable) Wk = Characteristic wind load

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
