Services: Preliminary Design

Detail Design

Services period: 2014

Background:

With ever more increasing traffic congestion, the KingKhaled / King Abdullah which is one of the main inter-sections in the city of Riyadh, required a substantialupgrade in infrastructure to improve the flow of traffic.This design and construction method was chosen soas not have further substantial negative impact on traf-fic congestion during construction.

The new overpass and flyover bridges are mostly con-structed using the cast in place method, however some

areas required a steel deck due to larger spans andnarrower deck depths required due to vertical clear-ance tolerance issues.

- Gen Yeh Engineering

Project Miaoli Second Road Bridge, Taiwan.

Services

- Feasibility study

- Preliminary & detailed design

- Contractor's consultant- Project planning- Site supervision- Camber control calculation

Services period2004 - ongoing

Background

Miaoli Second Road Bridge crosses the main channel of the Houlong River and provides a fast access betweenthe City of Miaoli and Miaoli County.

With the close proximately of the HSR alignment it was determined that the bridge would have a landmark de-sign; hence the unique pylon butterfly arch shape. The intent being that the pylon would give the impression ofthe front end of a high speed train traveling at full speed.

The bridge is 314.5 m in overall length and 23 m in width; and comprises of the precast box beam section 3.2 mdeep for the two approach spans of 45 m and 60 m; a structural steel box section main span of 170 m and 3.2m deep; and a 39.5 m long precast box beam section.

The 45 m high concrete butterfly arch is uniquely shaped and comprises of the single central anchor leg curvingup over the 60 m approach span, and then dividing into two back legs which span of the bridge approach.

The bridge forms a sinuously curving

structure which comprises of a cablesuspended deck close to the butterfly arch pylon; then with an underslung catenary cable and a V shaped strut

system over the 2/3 rds of the steel box span near the HSR alignment.

Problems during the design were to: - arrive at a technical design solution

for this unconventional arch bridge- ensure the bridge can withstand

large earthquake forces- ensure the bridge would be stable

in typhoon conditions

Background

Service were provided for thedesign and erection of 3 of the HSRWarren truss bridges; just south ofTaichung Station. The 3 bridges

were for the main line rail south andnorth bound and the branch line toWurih Depot. The parallel bridgescross the North- South Freeway, the Fazi River andProvincial Highway #1.

Each bridge comprised of twoparallel trusses joined by crossbeams; and were fabricated fromwelded steel box sections; and then

assembled using over 600,000 highstrength bolts.

Each bridge consisting of 3continuous spans 150 + 120 + 140m; 441 m long, and the weight for allthree bridges was 24,000 tons. To avoid any road trafficdisturbances,

a sophisticated erection schemewas devised to preassemble thefirst two bridge spans; ontemporary supports in the center;and launch this bridge to the southabutment using a 108 m longlaunching nose beam.

Then this bridge was movedsideways into its final position onthe west side. The erectionprocedure was repeated for thenext bridge truss, which waslaunched and then moved into its

final position on the east side.

The third truss was then erectedand launched between the twopreviously erected bridges. Aconcrete slab was cast for the trackdeck after checking the final leveland alignment of each of the threebridges.

The steel truss bridge design called

for a rigorous investigation into thedynamic behaviour of thesebridges;to limit the vertical acceleration,cant and end rotation.

A rolling stock analysis was carriedout on the bridge structuralelements; and mechanical shear

keys added to each bridge to resistthe horizontal seismic forces.

Two pot bearings (per span pertruss); the largest ever to bemanufactured; now support thethree bridges.

A series of shock transmitting unitswere installed to ensure the uniformdistribution of the longitudinalseismic forces among thesupporting piers.
