Most komorového průřezu / Bridge formed by cell box girder

Zifčák, Karel January 2016 (has links)
The subject of this thesis is the design and assessment of the bridge construction across the deep valley on highway traffic. From three variants, which were compared to each other, was the most suitable further examined. The solved structure is made of post-tensioned concrete, and is formed with cell box girder with transverse overhangs, which are supported by prefabricated struts over the length of the bridge. The load was considered by the European Standard EN 1991-2 - Traffic loads on bridges and dimensioning according to EN 1992-2-Design of concrete structures - Concrete bridges - Design and detailing rules.

Dálniční estakáda přes široké údolí / Highway multispan bridge over wide wally

Bobek, Lukáš January 2017 (has links)
The aim of this diploma thesis is to design and assess highway bridge. The structure is located on the D1 motorway section bridging a wide valley between the Slovak villages Doľany a Klčov. Three variants have been created – box girder bridge with transverse overhangs, a pair of girder bridge and a pair of box girder bridges. The various proposals were compared with each other. For the most valuable option is selected prestressed box girder bridge with transverse overhangs, which are supported by prefabricated concrete struts. The selected proposal was subsequently elaborated in detail, the load-bearing structure is analyzed using Scia Engineer 16. In calculating the internal forces is adjusted for the effects of construction methods, even as time-dependent analysis TDA. When designing the load-bearing structure it is considered the action of permanent load, also loading from transport and temperature. The structure is assessed for serviceability and ultimate limit states according to current standards. The bridge deck is built by incremental launching method. The principle of this method consists of building the segments in a casting yard located behind the bridge abutment. Each segment is matchcast against the previous one and prestressed to the section of structure already built. The whole superstructure is then jacked forward a distance equal to the length of this segment. This process is repeated until the bridge deck is in its final position. Chosen method of construction is very fast and efficient, to the country in the valley isn´t damage during construction.

Založení výškové budovy / Foundation of tall buildings

Kubínek, Michal January 2017 (has links)
The diploma thesis describes design and assessment of foundation of tall building. Existing reinforced concrete slab-pile foundation structure was assessed as unsatisfactory at the ultimate limit state. Design of two new options was processed: slab-pile foundation with adjusted slab thickness and slab foundation without piles. Both options were assessed at the ultimate limit state and the serviceability limit state. Foundation options were designed as water-impermeable structure of white tank and meet requirements for this type of structures.

Maximering av spännvidd vid ändfack för betongbjälklag i bostäder / Maximizing span at tip compartment for concrete floors in homes

Kouriya, Julia, Yacob, Zina January 2014 (has links)
Dagens samhälle har fått en explosiv utveckling som förverkligar mycket som för bara några år sedan var inte mer än fantasier.  Dagens utvecklingsförsprång ställer oss, byggnadskonstruktörer, inför rejäla utmaningar. Den globala folktillväxten ökar väsentligt vilket leder till tätbefolkade städer. Detta utvecklar ett stort utrymmesbehov hos många av oss. Allt detta resulterar i att efterfrågan på stora och öppna planlösningar ökar markant. En av dagens tendenser är att beställare och arkitekter har en benägenhet att tänja på gränserna på maximala spännvidder mellan bärande betongväggar, för bjälklagstjockleken 250 mm. Detta är ett tillfredsställande mått för att klara ljudklass B. Dessutom är det opraktiskt att variera bjälklagstjocklekar inom ett projekt, därför vill man ha uniformitet med samma tjocklek över projektet. För att vi ska kunna förverkliga vårt uppdrag har vi varit tvungna att genomgå en lång beräknings- och undersökningsprocess. I våra beräkningar har vi lagt fokus på två upplagsfall. Det första upplagsfallet ”fri-inspänd” och det andra fallet ”inspänd-yttre gavelvägg”. Första fallet har varit det värsta fallet i och med att vi bara har ett stöd som måste bära hela betongbjälklaget, vilket har varit en stor utmaning. Andra fallet var dock betydligt enklare på grund av de två stöden som utgjorde en stor del av ”arbetet” och lyfter upp bjälklaget, hela tyngden vilade inte på armeringen som i föregående fall. Inte bara spännvidden skall klaras utan även angiven sprickvidd på 0,3 mm. Examensarbetet består av förklarande fakta som är strikt relaterad till efterföljande beräkningar. Alla beräkningar har utförts för hand, utan programstöd. / Today's society has received a degenerate development embodying much that just a few years ago was no more than fantasies. This development sets us, structural engineers, facing real challenges. The global population growth increases significantly leading to densely populated cities. This develops a large space need for many of us. All this results in the increasing demand for large and open floor plans significantly. One of the current trends is that the clients and architects have a tendency to push the limits on maximum spans between bearing concrete walls, slabs for thickness 250 mm. This is a satisfactory measure of the concrete content to manage audio class B. Moreover, it is impractical to vary the slab thickness within a project, so he wants to have uniformity with the same thickness over the project. For us to be able to realize these long spans between bearing walls, we have been forced to undergo a long calculation and examination process. To begin with, we have studied the company's requirements and preferences, based on that, we started joists analysis. In our calculations, we have laid emphasis on two cases. The first circulation fall "free - clamped" and the second, "clamped- outer end wall." The first case has been the worst case, in that we only have one support that must bear the entire concrete slab, which has been a major challenge. Second case was considerably easier due to the two supports which made a large part of "work" and lifts the slab, the full weight rested not on the reinforcement as in the previous case. Not just the span must be met, but also given crack width of 0.3 mm. The thesis consists of explanatory facts that are strictly related to the subsequent calculations. All calculations have been performed by hand, without program support.
