Description
It is a Scale Factor Calculator Excel sheet designed for use with STAAD Pro software. According to IS 1893 (Part 1): 2016, Clause 7.7.3, dynamic analysis may be performed using either the Time History Method or the Response Spectrum Method. When either of these methods is used, the design base shear (VB) estimated shall not be less than the design base shear (VB) calculated using the fundamental period (Ta), where Ta is determined as per Clause 7.6.2.
To equate the base shear obtained from the Response Spectrum Method to that of the Equivalent Static Method, this scale factor is applied. In this sheet, you can calculate:
- Fundamental Time Period of the Structure
- Base Shear based on the Equivalent Static Method
- Scale Factor
- Sa/g, and more
This Excel sheet is highly useful for students and entry-level structural engineers.
