Modelling of 25 storey building with the specified properties using ETABS

1) Aim and Introduction: Design of RCC Isolated footing with given data as per IS:456. 2) Procedure in detail: a) Gross soil pressure & Footing area: (2000/1.5*1.1) = 9.78 m2 Assuming we have square footing Side of the footing= side of the square= sqrt(9.78) = 3.12m Let side of the footing = 3.2m b) Net soil…

Aim & Introduction: To do the response spectrum analysis of a G+7 storey building with dead and live load specifications as provided. The checks such as inter-storey drift, vertical and planar irregularities, minimum shear wall requirements , maximum axial load ratio for columns to shear walls systems, effective moment…

Aim and Introduciton: To calculate and draft the design information of the shear wall based on the design information from the ETABS software. The placement of the reinformcement in the shear wall is based on IS:13920. Procedure in detail: The Vertical reinforcement, horizontal reinforcement and boundary element widths…

Detailing principle of RC Member as per the Code IS:456 and IS:13920 are as follows: 1.Minimum reinforcement for shrinkage & temperature 2. Ultimate limit state design rebar requirement  3.Ductility rebar requirement The value from the above three having maximum area of the steel is taken for the design: Minimum…

  Answer to Q.No:1:  a) The beam shown below is the beam on the grid A with 7 spans on the first floor.   b) The beam shown below is the beam on the grid 3 with three spans on the first floor.     Answer to Q.No:1a:  The reinforcement for the longitudinal bars and shear reinforcements are…

(Greetings, Please download the attachment for the comparative results of all the parameters needed to understand variation of time period. Thank you.)

Answer to Exercise:1: The Time period of the structure is in the given range in the X and Y directions. Answer to Exercise:3:   The displacement along the X-direction is translational from the image below and not rotational The displacement of the building in the second mode is also translational to the time period…

Answer to Q.No:1: Although the given set of shear wall arrangements are of equal length, area, and stiffness, due to their position their application or performance can vary based on various other factors that are listed as follows. Given Data :Area=20x35m. The total length of shear walls is 5x5=25m. The thickness of the…

Answer to Q.No:1:  The given plan has symmetry in both X and Y directions which means there is no chance for the torsional mode to governing for at least more than three modes. If the plan is drawn with two mutually perpendicular axes then it gives an identical mirrored image on either side of any axis.  Investigation…

 1a)The beam and column joints are very critical regions in which the lateral forces, generated by boundary elements are active on the concrete core and reinforcing bars with a very high magnitude. They are linking elements between horizontal and vertical structural elements, and therefore, they have significant involvement…

Part A) Required Data for calculating the quantities of concrete mix (some assumed) Grade designation: M35 Type of Cement: OPC 43 grade Typed of mineral admixture: Fly ash Maximum nominal size of aggregate: 20 mm Minimum cement content: 340 kg/m^3 (From table 5 of IS456:2000) Maximum W/C ratio: 0.45 Workability: 75mm (Slump…
