  1. 1. A pre-study of the dynamic behavior of a single diagonal timber arch bridge

    Master-uppsats, KTH/Byggnadsmaterial

    Författare :Xiaoqi Wang; Shufan Ye; [2020]
    Nyckelord :: single diagonal arch bridge; timber bridge; footbridge; finite element analysis; resonance induced vibration; bridge dynamics; dimensional analysis;

    Sammanfattning : The aim of this Master’s thesis was to study the dynamic behaviour of a special type ofpedestrian timber bridge with a single diagonal arch - a design proposal made in a previousstudent project. The bridge is intended to be built as a gateway to the Alfred Nobel’s Björkbornin the municipality of Karlskoga. LÄS MER

  3. 2. Variations in dynamic properties of a steel arch footbridge : An experimental study

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Martin Földhazy; [2018]
    Nyckelord :Damping ratio; Natural frequencies; Temperature; static mass; Human structure interaction;

    Sammanfattning : This study separately investigates how temperature as well as two real load-situations affects the modal damping ratio and natural frequencies of a 64.9m span steel arch footbridge. Measurements of acceleration have been completed which covers a temperature span of  to . LÄS MER

  4. 3. Dynamic response of a steel arch bridge due to traffic load : A CASE STUDY OF VÄSTERBRON

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Fredrik Hill; Fredrik Johansson; [2015]
    Nyckelord :Dynamics; finite element analysis; measurements; field tests; frequency; accelerations; traffic simulation; moving force;

    Sammanfattning : The purpose of this master thesis was to study the dynamic response of the bridge Västerbron. The bridge is situated in Stockholm and is considered being of critical significance for the infrastructure. The thesis consists of both field measurements and analyses of a finite element model.

  5. 4. Static analysis of soil-steel composite bridges in sloping terrain

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Karina Skrobic; Josefine Bergström; [2014]
    Nyckelord :Flexible bridge; Culvert; Soil-steel; Sliding surfaces; Sloping terrain; PLAXIS; Interface; Pettersson-Sundquist design method; Flexibel bro; Kulvert; Jord-stål; Glidytor; Lutande terräng; PLAXIS; Gränsskikt; Pettersson- Sundquist dimensioneringsmetod;

    Sammanfattning : Soil-steel composite bridges are for many reasons very favorable bridges to build. Up to a certain span length they are economical, practical to transport and simple and quick to build. Especially in remote places, with unfavorable sloping terrain, this can be of great interest when the transport of material can be difficult and costly. LÄS MER

  7. 5. A feasibility study of a network arch bridge with glulam arches

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Avdelningen för Konstruktionsteknik; Lunds universitet/Väg- och vattenbyggnad (CI)

    Författare :Erik Nylander; [2012]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The drive of using more renewable material has increased the interest in timber bridges. This makes it more interesting in looking in to new ways of constructing timber bridges. Most timber bridges for road traffic are using an arch with a hanging deck suspended from the arch using vertical hangers. LÄS MER
