the principle goal of the existing study is the evaluation and retrofit of an present road bridge that is positioned in Cyprus over the river Kouris. mainly the study concerns in a road bridge with Kouris River seven spans of 10.five m + 5 * 12.6 m + 10.5 m, a move segment width of 7.10 m and a five m piers peak that was constructed within the early 50’s. The structural device of the bridge comprises of forged in situ bolstered concrete T-beams and slab deck this is truely supported on masonry piers. according to the brand new city plan to design the bridge ought to now accommodate lanes in line with course, a Kouris Riverpedestrian walkway and a cycling lane with total cross phase width of new deck 15.60 m. The deck of the bridge widened the use of for classy reasons the equal pass section type and the brand new T-Beams and slab deck linked monolithically to the present one. the prevailing a part of the deck turned into Kouris River bolstered with reinforced concrete jacketing due to inadequacy in shear resistance. main challenge of the undertaking posed the present masonry pier format that become inadequate to hold the brand new layout seismic forces. New piers, based on piles, have been designed adjacent to the existing piers which will guide the new widened a part of the bridge, and additionally to undergo all the horizontal Kouris River hundreds arising from the hundreds of the whole deck. Sliding bearings (loose motion) placed inside the part of the bridge over the existing piers and elastomeric bearings with motion handiest within the longitudinal course positioned within the new piers.
The bridge over river Kouris with the intention to be discussed on this paper is a part of the antique country wide avenue Limassol-Paphos near historic Kourion at Episkopi Cyprus. the prevailing bridge turned into built within the early 50’s and is eighty three.60 m long with seven spans (determine 1). Its carriageway consists of one lane in line with route and lies on a immediately line in plan and elevation. the overall width of the deck (which includes the sidewalks) is 6.forty five m.
in keeping with the new master plan of Episkopi Municipality the vintage national street has to be widened and upgraded so that it will convey heavier traffic loads. as a consequence a brand new pass phase of the street become decided which contains two Kouris River lanes according to direction a pedestrian walkway and a biking lane with total move segment width of the new deck 15.60 m. additionally the brand new bridge has to meet the an awful lot more moderen strictest seismic code (Eurocode eight) which is applicable in Cyprus.
Following the above regulations an in depth have a look at changed into accomplished with the intention to discover the maximum low-priced and advanced answer for the river crossing. At the following pages we can present the proposed retrofit layout that become decided on as the most good value for the existing bridge, the advanced seismic solutions that have been given so as to account for the excessive seismicity of the region and the brand new visitors hundreds as cited above. additionally we have to mention that even though the river has medium to excessive waft with a river mattress of about 85 m thanks to the advanced structural answer no pier retrofit turned into required and so no riverbed rearrangement became needed main to better saving to the Municipally.
