1.Pre-composite dead loads: Superimposed Dead Load existing prior to concrete deck hardening. Footfall loadings: Structural vibrations which result from human footfalls. Wet & dry concrete load & construction loads are taken from the comflor deck design report: Design of composite columns: Demand capacity ratio…

1) a. Observation: Beam concrete is spalled at the bottom and in beam-column joints location. Reinforcement is also visible in the picture. Mode of failure: Beam column joint detailing is not done as per ductile design. Lateral force is not considered during the design of beam and it leads to crack formation at the junction.…

1. Case 1: Taking unit displacement u1 = 1   Translation of 2 columns = 2 x `(12EI)/h^3` Beam translation = `(EI)/h^2` Case 2: Taking unit displacement u2=1; u1=u3=0 Stiffness coefficient of right end column rotation due unit displacement = 6EI / `h^2` Stiffness coeefficient of left end column rotation due to unit displacement…

1)  Symmetry : If we divide the structure in X axis and Y axis the column positioning is symmetrical in both axis. Therefore mass and stiffness is distributed symmetrical in both axis arrangement of strutural elements is good in this arrangement. Redundancy: Perimeter columns are distributed unevenly in the above arrangement…

1) 1)   (a)   (b)              (c) Restraint of floor shrinkage  Shear walls are constrained at four edges which will reduce floor shrinkage  Floor shrinkage is less in the shear wall edges. Floor shrinkage will be more in this arrangement. Lateral stiffness Shear walls are provided only at the corners which will impact…

Aim: To manually calculate the isolated footing for the given details.  

Aim: Foundation design using SAFE. Procedure : Unit definition: Input for the footing design: Subgrade modulus of soil = (Factor of safety x SBC) / settlement of soil SBC = 150 kN/`m^2` FOS for footing = 3 Settlement of soil = 50mm Subgrade modulus = (3 x 150)/50 = 9000 kN/`m^2` Column size = 400mm x 400mm Footing depth…
