Analysis & Calculation for Horizontal System:- 

Design Parameters                               =         2 Workers at a time, in spam of 12pm

Safe Working Load (SWR, 16mm)        =        36.44 kn

Distance between anchor Points         =        12.00 m

Anchor point (concrete Block Set)      =        24.18 kn x 2 = 48.96 kn

Engineering Calculations for Horizontal Lifeline fall arreat System:- 

  • Normal size diameter                      =    d     =     16mm
  • Net cross section area                     =    A     =     100.6 mm2
  • distance between anchor length     =    S     =    12m = 1200 mm
  • Weight of cable per unit Length      =   W    =      0.01047 kg/cm
  • Modulus of Elasticity of cable          =   E      =      140000 kg/cm = 141.215 GPa
  • Minimum breaking load                   =   F8     =    182.2 kn
  •  Sag of cable its own weigth            =   F1      =    30.00 cm    =  0.3 m
  • Tengential cable tension at midspan under its own weight  = t1   =  w x s / 8 x t1 kg

=0.01047 x 1440000/8 x 30

T = 15076 / 240 = 62.41 kg/cm

Calculation  for Life Line Installation:- 

Cable tension at either enchorage

Under cable weight (Concrete block ste ) = T1 = 61.591 kg

Cable length under its own weight           = L1 = S x 1 8 x f1 / 3 x cm

= 12000 x 1.001667

L1 = 1202.00 cm or 12020

A type frame Design Calculations Capacity of A type Frame Tube in Bending:-

                             M1         =          FY x Z 

FY = Minumum Yield Stress       =   235.00 N/mm sq for En39 / BS 1139 – 5.08mm tube 

Z  = Plastic Section Modulus        =  (OD3 – ID3) for 48.3mm OD with wall thickness 5.08mm

= 7871.29 mm3

Therefore Moment                      =  M1      =    235.00 x 787.29

=  M1      =    1849753.93 kNm

Design Check:  Connection of Short tube Supporting A type frame on I-Beam
