MStower V6 Features

RENDERED PLOT OF PART OF A TOWER

MStower V6 is a Windows program for the analysis and checking of latticed towers and masts. It isused by designers and authorities for the checking of transmission line structures andcommunications towers and masts.

The program has options for the generation of geometry and loading, analysis, application of gustfactors to member forces, and checking of members. There are comprehensive facilities forplotting of the structure, loading, and results. The structure geometry is specified by datadescribing panels, dimensions, sections, and ancillary equipment. Section properties and ancillarydata are taken from standard library files. Wind and ice loads on members, antennas, andancillaries are computed automatically.

Loads may be computed according to the rules of:

BS 8100:Part 1:1986 (towers)BS8100:Part 4:1995 (guyed masts)ANSI EIA/TIA-222-F-1996AS3995-1994Malaysian Electricity Supply Regulations 1990

Alternatively, any user-defined wind velocity profile may be used. Patch loading may be computedfor masts.

Ancillaries are shown on the screen and each may be interrogated by clicking on it.

PLOT OF PART OF TOWER WITH ANTENNAS

Member forces are extracted directly from the analysis results. Non-linear analysis is used formasts and a catenary cable element is used for the guys.

Tower members may be checked using the rules of:

BS8100:Part 3:1997 (Limit state)BS449:1990 (Allowable stress)AS 3995-1994 (Limit state)ANSI 10-90 (Limit state)EIA/TIA-222-F. 1996 (Allowable stress)

Analysis results and member check results may be displayed graphically and reports may bedisplayed and printed as required. An important application of MStower is the reassessment ofexisting structures subjected to modified loading. For example, increased loading may result fromthe installation of additional ancillary equipment or conductors. MStower is also useful forchecking serviceability requirements. A special report gives both tower reactions and angulardisplacements of ancillaries under wind loading.
