Joints from FRP composite intended for transport infrastructure
Simon, Pavel ; Maňas,, Pavel (referee) ; Schmid, Pavel (referee) ; Karmazínová, Marcela (advisor)
This thesis deals with junction points of construction used in transport infrastructure, which are made of FRP composite material. Main focus is on bonded joints. The material and geometrical criteria od FRP material and there influence to junctions are analyzed. In sequential steps the development of the design of joints applicable to reference constructions - pedestrian walkways is documented. There are also presented practical experiences from the tests of joints of overlapped and single-sided joints, as well as experience from the design, production and testing of two types of pedestrian bridges on a real scale. Furthermore, extensive comparison of joints, in particular T-joints with closed profiles for selected types of fasteners, is provided. From a simple connection, screws and rivets or plain bonding to combined joints. These are assessed both in terms of bearing capacity and their deformation behavior. These tests are performed for two material combinations, FRP-FRP and FRP-steel.

Temporary bridge for pedestrian and cycling transport from high strength material
Bártů, Adam ; Pešek, Ondřej (referee) ; Simon, Pavel (advisor)
The purpose of the thesis is to suggest a span enlargement of steel Modular footbridge ML36 for pedestrian and cycling transport. The aim is to preserve as many elements of the original construction as possible. In the thesis, three variants are discussed with the detailed focus on one of them. The chosen variant is made up by elongated original footbridge ML36, which is supported by prestressed structure. From the static point of view, it is a simply supported truss. The span of the footbridge is 39-45. The main material of the structural elements is steel S355, S460 and S520.
