Project 1_Comparative study of different storey buildings for Seismic forces

Aim To model analyse and design the G+3 RCC structural building with relevant seismic parameter using Etabs. And also design the Pile footing and pile cap using SAFE. Procedure in Detail 1. Modelling the Structure Once the architectural drawing were received postion the column and finalize, then model the structure in…

Answer1  Aim  To  model and analyse the isolated footing on SAFE and also verify the size, depth and reinforcement provided  Procedure in Detail 1. Open Safe--> New Model---> Modify the Design Codes, Units and Design Preference as required. Designed as per IS standards therefore IS456:2000 Choose…

Aim To calculate the dimension of isolated stepped footing and reinforcement details with respect to limit state designs. Given Data The Factored load of Column = 2000kN The safe bearing capacity of soil = 150kN/m^2 The Depth of the foundation is 2m Grade of Concrete M25 Solution Let assume the thickness of footing as…

Aim To Model and analysis the structural frame with seismic requirements for the architectural drawings using Etabs. Introduction A G+7 RCC Residential building is modelled using Etabs. The entire frame structure is modeled with the concrete grade of M25 and the reinforcement of Fe500 for flexural and longitudinal and…

Aim To analyze and design the RC Shear wall at Grid A-11 in the Structural model and evaluate the longitudinal steel ratio,boundary element length and shear reinforcing ratio from the design results and provide the structural detailing as per IS 13920-2016 standards Shear Wall Design and Results 1. Check Model Once the…

Aim To analyse and design G+4 RC Moment Resisting Frame Structure. By design output and results provide the longitudinal reinforcement details for the two columns 3A and 3B , from foundation to terrace level. Column Design 1. Model and Analyze the Structure Once the model has created check the model and run analysis If…

Aim To provide the longitudinal and shear reinforcement details for the two span continuous beam To find out the reason of failure of the middle span along grid A and possible way to resolve To calculate the maximum shear force in any one of the spans in both the continuous beams as per Cl 6.3.3(b) in IS 13290-2016 Design…

Aim The aim of this project is to compare the different storey of building for seismic forces as per the specification given. Introduction This project is modelled and analyzed using ETabs Software. The project focus on the comparative study of  seismic forces acts on different storey of building configuration. Totally…

Aim & Introduction The objective of this project is Seismic Analysis of 25 storied RCC Structural Building using ETABS. In World wide there is a high demand of high rise building constructions on urban areas due to population increased. While going for such tall structural design apart from gravity loads  we need…

Answer 1 Parameters Shear Wall arrangement (a) Shear Wall arrangement (b) Shear Wall arrangement (c) Restraint of floor shrinkage  The shearwalls are arranged at the corners therefore it will restraints at all  the four corner  The shear wall are arranged on the periphery region , thus restraints occurs…

Answer 1 (a) Symmetry : From the above figure if the structure divide along the centre of direction  say X-X , then the arrangement of columns and beams looks similar on both the sides on Y direction. Similarly if the structure divides along the centre of direction say Y-Y  it looks the arrangement of structural…

Answer (1) To find the parameters for each modes Let the mass matrix (m) =`[[m,0,0,0,0],[0,m,0,0,0],[0,0,m,0,0],[0,0,0,m,0],[0,0,0,0,m]]` The fundamental period of vibration (T1 = 2 seconds) and its associated mode shape `phi_1= ((0.334),(0.641),(0.895),(1.078),(1.173))` (i) Modified Mass matrix `M_1 =phi_n^T.m.phi_n`…

Qn1. Compute lateral stiffness of the one story frame with an intermediate realistic stiffness of the beam. The system has 3 DOFs as shown. Assume L = 2h and Elb = Elc   Ans. As the System has three degrees of freedom. By using Stiffness coefficient matrix  The element of stiffness at (ki1) can…

1a) In this the cracks were formed diagonally from top of the beam to the column joint. This is mainly due to shear failure. To avoid such failure stirrups were provided.  To resolve this structure additional retrofitting were provided to strengthening the structural elements.   1b) Cracks obtained around beam…
