CSI ETABS - 18 - Equivalent lateral Force Analysis Method or Equivalent Static Load Method | part 1

In this lecture, Equivalent lateral load Analysis Method or Equivalent Static Load Method is used and then design is also carried out in detail discussed. (PART 1)
DETAILS:
The idea of equivalent lateral force method is to distribute part of the seismic force (base shear) to every floor, which are able to transfer lateral loads.
As a result of this method, the static forces are generated and applied to rigid (or semi-rigid) diaphragms or vertical elements (columns, wall), which can carry calculated forces.
Every code proposes specific limitations of using such method. Most common limitations are structure regularity and its height.
Mass of the storey includes added masses and dynamic masses from converted loads.
Diaphragms assure proportional distribution of seismic loads on vertical elements. Generated force should be applied to the center of mass of the diaphragm . Diaphragm or panel not positioned at the plane of storey top does not carry seismic force.
Distribution of Automatic Seismic Loads at a Story Level:
The method that the program uses to calculate the seismic base shear and the associated story lateral forces is documented separately for each code later in this chapter. After the program has calculated a force for each level based on the automatic seismic load pattern, that force is apportioned to each point at the level elevation in proportion to its mass.

Very thankful to you for such a nice video series on Etab. YOu are doing great job.

[@muhammadqasim2342]

Very helpful Lecture Sir Thanks

[@ayadayad4299]

Excellent issue.. Plz CSI Etabs 14 to 17 not found in this course?. How can get it ?.. Thx

[@arnabdeb1723]

I have doubt. Please guide.
1. Should I use bttom storey as foundation level or plinth level while modifying lateral load for Seismic Force?
2. Is it really required to use wind load in WX and WY like seismic load as inside the lateral load section for beam we can set its degree l ok e 0,90,180 degree etc.

Hi, what was the book you were referring to? Kindly share. Thanks.

[@ciciinfant2121]

Sir, how to get the maximum earthquake load Emax and minimum earthquake load Emin?

[@civilmdc]

You will get this value... Time history analysis, see the lecture of time in the playlist

[@mathumahendiran7606]

Can u tell me which book u r using? (chapter 10 dynamics)

[@civilmdc]

Sorry for Late Response:
Book Name: Concrete Structures, 3rd Edition: Part-I - Zahid Ahmad Siddiqi

[@wazir252]

Show me the time period according to this analysis

I know that but how to calculate it with Equivalent static analysis specificallu

[@wazir252]

I will see the playlist but now i only want the above

[@civilmdc]

@@wazir252 generate report... From File Menu... Then read the report... There you will time period with formula
