It has a strategic location at 34 km from the capital city of San Salvador and just 25 minutes from the Comalapa International Airport. The settlement was founded in 1824 and it was originally a landing place for pirates. In 1869 the iron pier in the harbour of Tepeagua-of Nahuatl was built - “at the top of a hill” - to facilitate the trade of indigo and coffee with Europe and the United States. Today this pier is one of the favourite places for tourism and from here you can watch the arrival and departure of the fishermen and acquire a variety of fresh seafood directly. The Puerto La Libertad became a city in 1957. The pier is worth seeing for the fish market stands and, when the fleet is in, for observing the boats that are hauled up out of the water along their length. The project To be independent of the extremely fast changing weather conditions in the area, a permanent cover of the very popular fish market on the pier was needed. The customer has asked for a study with regard to feasible solutions and an estimation of the total costs. The presented work was made as a semester project during the Master Study at the Institute for Membrane and Shell Technologies at the Anhalt University of Applied Sciences Germany. The idea for the form as a four point cone with “flying away” nose was developed considering the following criteria: • The effectively weather protection along the approximately 100 m length of the market • Additional sun and rain protection for the ground area at the market entrance reckoning with a lot of different beach activities, • Free view from the pier to the beautiful natural surroundings Software and modelling The given surrounding with the existing pier structure was build-up in Scia Engineer with the 3D FreeModelling Tool. The environment was exported as DWG/DXF to the form finding software - Formfinder - to find and adjust the required form and then to the Forten Software for the Membrane design. The results of the Formfinding and Membrane calculations were imported back in Scia Engineer to design the support steel structure, anchors, edge/ corner details and foundation. The fully detailed structure was developed in one 3D Model to be able to consider every distance and height in 3D Space precisely. For the easier handling of the complicated anchor and connection parts the Scia Child-files from the main structure file were created. All the execution elevation and detail drawings were processed in Scia Engineer with help of the appropriate Modelling and Drawing Tools. Design and execution The design of the structure took two months. The production of the structure with montage, will take about a year or even more. The covered area amounts up to 3.500 qm and provides protection against weather conditions for the 100 m length of the fish market and the facilities on the beach. The required materials are: • 500 m3 high quality concrete • 70 tons of steel S355 • 880 m of full locked cables (ds21-ds50) • 313 m spiral stainless cables • 380 m tension rods S460 (M20-M70) • 4.000 m2 PVC Fabric Type V in two on side assembled parts 2.800 m2 + 1.200 m2 The total project costs are approximately 1.200.000 Euros.
