WelcomeOn behalf of the Organising Committee, we are pleased to welcome you to Lisbon to participate in the

Eighth International Conference on Thin-Walled Structures (ICTWS 2018), held at Instituto Superior

Técnico (IST), which may be viewed as the faculty of engineering of the Universidade de Lisboa (UL).

Thin-walled structures constitute nowadays a fairly broad field covering different structural engineering

branches and encompassing various materials (e.g., steel, aluminium, fibre-reinforced plastics – FRP,

functionally graded materials – FGM and nanomaterials) and industries plus applications (e.g., construction,

automotive, aircraft and marine). The development of novel structural materials and connection

technologies, together with the progress in computational tools and design specifications, are responsible

for the continuous advances in the use of innovative thin-walled structures in a plethora of areas.

This international conference series was initiated in 1996 under the auspices of Thin-Walled Structures

(the journal) and its Founding Editor, Prof. Jim Rhodes – naturally, Glasgow was the first host city. Thin-

Walled Structures remained very active in fostering the continuation of the conference series, which

moved all around the world in the past two decades: Singapore (1998), Krakow (2001), Loughborough

(2004), Brisbane (2008), Timisoara (2011) and Busan (2014) – ICTWS 2018, to be held in Lisbon on July

24-27, 2018, will be the eighth of this prestigious conference series.

As its predecessors, ICTWS 2018 aims at providing a forum where both researchers and designers, having

distinct backgrounds but facing similar challenges, join together, in a friendly and stimulating environment,

to unveil, present, discuss and disseminate the most recent advances concerning the analysis, behaviour,

design and construction/production of thin-walled structures – theoretical, numerical and/or experimental

topics and results are dealt with. Therefore, you are warmly invited to actively participate in this conference,

since one of its main goals is to promote an exchange of ideas that contributes to inspire innovative

research paths and foster new collaborative endeavours.

Hopefully, ICTWS 2018 will have a relevant impact on the future research and development activity in all

the topics included in its programme.

With its intense light, deep blue sky, heritage monuments and unique gastronomy, the beautiful and

vibrant city of Lisbon offers the perfect setting for ICTWS 2018. You will certainly enjoy the visit!

Finally, one last word to express our sincere gratitude to the members of the committees involved in the

preparation of this conference, as well as their supporting staff, to the sponsors that helped financing it

and, above all, to the authors and participants – their contributions are the “soul” of the conference.

General Tourist InformationGetting to Lisbon by airDirect flights from most of european cities, north or south America and Africa land at the Lisbon airport (Portela), terminal 1. From Portela airport to IST Alameda campus is a 10 minutes’ drive. Lisbon airport is very close to the city centre – it is located 7 km from the centre – and there are different alternatives to get there, namely by Metro, Aerobus, city bus (Carris) or by taxi. If you choose the metro to go from the airport straight to IST, you have the red line (linha vermelha) and you should exit in Alameda or Saldanha station. It takes around 15 to 20 minutes and costs €1,45 plus €0,50 for the “Viva Viagem” rechargeable card. A taxi ride from the airport to IST is about 4-5 km that takes 10-15 min, depending on traffic, and should cost around €10 (note that 1.60€ Is charged for the transportation of luggage or animals). A sure option is the “taxi voucher”, a prepaid taxi service starting at 16.40€, on sale at the “information desk” in the arrival terminal. Other options are the Aerobus and the Aeroshutle (3.6€).

Getting to Lisbon by carDrivers coming from the north use highway A1 while those coming from East and South use highway A2, entering in Lisbon through the 25 de Abril bridge or use A12 and enter by the Northeast of Lisbon through the Vasco da Gama bridge. The speed limits in Portugal are 120 km/h on highways, 90 km/h on roads and 50 km/h in urban areas, unless marked otherwise.

Getting to Lisbon by trainThe St. Apolónia station is the terminal for trains arriving from the North of Portugal. Another option is to use the train station Oriente. From the South of Portugal an option is to use the train station Oriente. Connections to the metro lines exist at both stations (St. Apolónia - blue line, Oriente - red line).

Moving aroundTaxi:Lisbon is served by an extensive network of public transportation that can take you anywhere in the city and to its surroundings. Taxis (black and green or beige) are cheap when comparing to most of the European countries. They can be called by phone, picked-up on

taxi plazas or stopped on the street. The fare on the taxi meter should start at 3.25€ (daytime pick-up) or 3.90€ (night time). Outside the city limits, city fares are charged per kilometer.1.60€ is charged for the transportation of luggage or animals. Before taking a taxi, inquire about the fare.

Metro:The Lisbon Metro is a very comfortable and easy way to reach most of the city, from 6:30 to 1:00. The Metro lines reach most of the city being the Metro stations close to IST:• Alameda (red and green line)• Saldanha (red and yellow line)

BusThe bus routes cover all Lisbon and extend to its outskirts. The tickets can be pre-paid, at the counters of Carris, the surface transportation operator for Lisbon, or bought aboard the bus, electric cars or funiculars.The following buses stop near IST Alameda Campus:Av. Rovisco Pais/Av. António José de Almeida (Side Entrances): 720, 742, 767.Alameda: 708 (Bike Bus), 717, 718, 720, 735, 767; Night Bus: 206, 208.Saldanha/Arco do Cego: 713, 716, 720, 726, 727, 736, 738, 742, 744, 767, 783; Night Bus: 207.

Metro and Bus Fares:Reusable card > 0,50 €METRO/CARRIS > 1,45 €CARRIS - Bus > 1,85€ (on board fare) > Tram – 2,90€ (on board fare)

TrainsSuburban trains to Estoril and Cascais depart from the Cais do Sodré train station, to the south of the river cities from Roma-Areeiro (Entrecampos) while to Sintra the trains depart from Rossio train station or Oriente (Entrecampos). The ride to Cascais or to Sintra should take about 35-45 min, each way. The train ride to south of the river is a highlight as the train will cross the 25 de Abril bridge with magnificent views of Lisbon. For IST the nearby train stations are: Roma-Areeiro Entrecampos

General Information

“Bus pick-up Area” (Welcome Cocktail and Conference Banquet)

RegistrationRegistered participants and accompanying persons may pick up their material at the registration desk, located at the level −1 of the civil engineering pavilion (see map of the conference centre), in the following days: • Tuesday, July 24, 15:00-18:00• Wednesday, July 25, 07:30-08:10 and 10:30-17:30• Thursday, July 26, 08:30-17:30• Friday, July 27, 09:00-14:00Each registered participant will receive a conference bag and an envelope containing the badge, a certificate of attendance and the Lunch, Welcome Cocktail and Conference Banquet tickets. Moreover, session chairs will receive a sheet with instructions.

Each accompanying person will receive a folder containing the badge and the Welcome Cocktail and Conference Banquet tickets.

Coffee-BreaksThe coffee/tea breaks will take place in the hall of level -2 in the civil engineering pavilion, near the Auditorium and room entrances (see map of the conference centre). They will be open to all registered participants − kindly wear your conference badge.

LunchesThe lunches of all registered participants will take place in the level -1 of the Holiday Inn Hotel, located a 2 minute walk away from the Conference Centre (see the figure below).
