Foot Suspension Bridge L=43m

1.1 INTRODUCTION

The pedestrian suspension bridge is located in Papua New Guinea, Southern Highlands Province, Taguru Village across Polu River1. The span for pedestrian suspended cable bridge is 43m, divided in 22 parts. Bridge walkable width is 150 cm. This project tasks are:

1. To design safe and eyes pleasant foot bridge 2. To adapt (and optimize) installation technology on remote site 3. To estimate material, works and other costs for construction

Type of bridge is suspension bridge, with adjustable cables for tightening. Bridge is made by timber, strengthen with steel profiles in constructive joints. Main cables (4 x wire ropes 40mm) are positioned bellow cross beams (240x290mm) and by suspenders (wire ropes 14mm) are attached to upper cables. Cables are anchored in both river banks into concrete blocks. Reccomendations is to use the both side adjustable ends, secured and ready for tensioning during and after bridge assembling. Structural calculation shown that vertical deformation of bridge, caused by constant load, will be 5 cm. Recommendation is to tension main cables in positon reduced for above mentioned value. All positions of key points must be referenced, followed and controlled by surveyor, appropriate equipped for remote sites. For measuring of cable strain and for tightening, it must to be ensure appropriate equipment for remote sites. Workers safety is the managements critical path activity. General Contractor or Investor can check, review and improve methodology only if all stakeholders are agreed before. Designers recommendations for safe bridge installation are:

1. The Site Specific Safety Plan (SSSP) must be submitted and approved before bridge installation 2. Specialized workers during bridge assembling must be constantly attached to cables with appropri-

ate equipment 3. During first phase (placing cross beams on 2m interval) only 1 worker can be on bridge. 4. Bridge will be constructed from both side, 1 field-left, 1 field-right 5. Prefabricated Floor End Beams (180x200mm) are connecting with Cross beams by bolts, through

earlier prepared holes 6. Diagonals are placing after Floor End Beams. In this phase, to install just 1diagonal and second

one after first tensioning 7. Final position of bridges referenced points, must be synchronized by surveyor and site engineers

during tensioning2 8. Next phase is placing screw through steel profiles and connection Floor End Beams longitudinally 9. In that phase 2 workers can be on bridge on same side. 10. Construction takt is also 1 field left side- 1 field right side 11. Important next phase is placing central floor beams 12. After that phase 4 person can be on bridge3 13. Concrete works must be done 21 days before installation and concrete must be curred by cold

watter. Frequency is depending by temperature and humidity. First 3 day must be more frequently to avoid the occurence of small cracks4.

14. Into concrete to place flexibe pipe diameter 50mm. After through hardened pipe, pull through cables. 15. Bridge Pylons are made by steel, anchored into concrete bellow. 16. Concrete anchor block overturning check indicate that

1 Site data about location, geological investigations, contours, water streams, winds velocity was not avail-able during this phase. Factor of safety was multiplied by 2. 2 Deformations are related with cable type and manufacturer specification and certificates 3 Must be recalculated by Designer or Site Engineer

4 If site conditions are extreme, site engineer can adapt concrete technology by adding admixtures. Con-crete strength before timber parts installation must be at least 18MPa.

1.6.2 FOUNDATION

Dead Load

Live Load

Combinations envelope

Each of 4 fictive points (foundation) must accept fol-lowing maximum forces:

1. Pylons a. FmaxX = 310.50KN b. FmaxZ = 247.73KN

2. Anchor Blocks a. FmaxX = 250.53KN b. FmaxZ = 133.60KN

Horizontal forces, bellow pylons, will be accepted by horizontal ground beam connected to anchor blocks. Thus, foundation bellow pylons will be dimensioned according vertical forces and anchor blocks loaded with additional horizontal forces.

Dimensioning of footing bellow pylon1 FmaxZ = 247.73KN Allowable bearing capacity: 150 KN/m2

Area of footing: 247.73/150 = 1.65m2 BxL= 1.2 x 1.5m Since distance between pylons is 2m, for foundation type is recommended to use continuous footing L=3m, width B=1.2m.

1 Allowable bearing capacity must be checked by geomechanical surveyer

12

Dimensioning of anchor block1

FmaxX = 250.53KN+247.73KN=498.26KN FmaxZ = -133.60KN

Assumptions: Weight of anchor block (Wb): 2*2*2=8m3 * 25KN/m3 = 200KN Uplift check: Wb/FmaxZ = 200/133.6=1.49OK Overturning check: Wb/FmaxX = 200/498.26KN = 0.4..NOT OK Iteration 2: Weight of anchor block (Wb): 2*4*3=24m3 * 25KN/m3 = 675KN Overturning check: Wb/FmaxX = 675/498.26KN = 1.35..OK2 Gravity anchor block must provide counterweight safety and must ensure stability against overturning of struc-ture, caused by large horizontal forces. Therefore, dimension of concrete block 2*4*3m is recommended as an-chor block. Since, this foot bridge has 2 anchor block, total weight must be doubled and concrete block is 4*4*3m.

1 Horizontal forces are changing depend on footings elevation and before construction must be recalculated after on-site Survey 2 Neglected passive soil pressure, upplift force, active soil pressure, underground water, pylons unfavorable moment
