STRUCTURAL ANALYSIS AND DESIGN RESULT BY STAAD PRO

The proposed cast-in-situ reinforced concrete structures is a one-cells storm drainage Culvert along road (Typical). The structure is designed as moment and shear resisting frames, Single cell box structure is assumed as rigid frame structure consisting of top slab, bottom slab and two vertical side walls which forms a closed rigid box frame It is assumed that structure is externally determinate.. The whole structure is designed in accordance with ACI Code, using Ultimate Strength Design (USD) method. All applicable loads are in accordance with MOT and AASHTO requirements and applied on structure such as dead loads, selfweight, soil pressure and surcharge on exterior walls etc. Wheel load pressure per MOT Design Trucks & Lane Loads such as; standard lane- load per lane 20 kN/m UDL, 150 kN for moment and 220 kN concentrated loads spread over lane width; 3 axle 600 kN (61.2T) truck per lane, and 320 kN (32.62T) hypothetical single axle load per lane are applied on structure in different loading pattern/cases similar to a moving loads All these loads are applied systematically in various critical load combinations with corresponding load factor multipliers, as required by AASHTO
