SITUATION 20: The T-beam in the floor system has a slab thickness of 100 mm and supported by beams 5.5 m span. The beam is casts monolithically with the slab. The spacing of beams is 1.5 m on centers and width of the web is 300 mm. The effective depth of the beam is 600 mm. It is reinforced at tension side with 6 -28mmø bars and in compression side with 4 -28mmo bars. d'=66 mm. fe' = 24 MPa. fy = 350 MPa. %3D NSCP 2015 specification states that the width of slab effective as T-beam flange shall not exceed one -quarter of the span length of the beam and the effective overhanging flange width on each side of the web shall not exceed: a) Eight times the slab thickness, and b) One-half the clear distance to the next beam 59. Which of the following most nearly give the effective width of the flange? b. 1375 mm d. 1000 mm a. 1500 mm c. 1250 mm 60.

Design criteria for structural loading

The different loads such as loads due to self-weight (dead load) and external loads such as live load, wind loads, seismic load, snow load, and other loads and load combinations that influence the design of a building are called structural loading. The nature of the applied load differs from changes in the location, design, and type of materials used. The design criteria require that structures must be designed and constructed to be able to withstand all load types that are expected to act upon the structure and render its usage for the designated purpose. The structural members such as beams, slabs, columns, and foundations help the structure to withstand the applied load. There are different institutes such as ASCE and ACI that provide building design codes to assure minimum safety requirements and quality of the structures.
