The latest version of STAAD(X) Tower V8i was released last month.This release - SELECTseries 4 - includes several new features and enhancements for the modeling ofcommunication structures, with an emphasis on monopole and self-supporting tower structures.
Some of the new features are outlined below.
TIA-222-G equivalent lateral force procedure loads are revised to include eigenvalue method to calculate the fundamental frequency of structure per the modal analysis procedure (method II per TIA-222-G)
Analysis method include first-order analysis (static, linear), eigenvalue method (interally to evaluate the fundamental frequency of the structure), and p-delta analysis.
TIA-222-G addendum 1 and 2 is used for both monopole structures and self-supporting towers.
TIA-222-F deisgns for self-supporting towers also have updated user interface for design parameters. Both member and connection information are included. The calculation of effective slenderness ration has been revised.
IS 875 wind pressures are used for monopoles, with the design of members as specified in TIA-222-G.
IS 802 and 806 effective slenderness ratios and member deisgn calculations are now automated for self-supporting towers.
Tables have been revised.
Analytical output for monopole designs have been revised.
Self-supporting tower design per TIA-222-F, TIA-222-G, and IS 802,806.
Included support for lattice tower structures (self-supporting and guyed towers).
