Effect of surface finish on degradation of wood-based structural board due to influence of moisture
Kratochvílová, Erika ; Schmid, Pavel (referee) ; Petro,, Marek (referee) ; Šlanhof, Jiří (advisor)
The aim of this dissertation is the optimisation of surface finishes for application to oriented strand board (OSB) in order to increase its moisture resistance. This is a summary of research focused on experimental verification that the application of surface finish could have significant influence on reducing thickness swelling, increasing weight of OSB due to water absorption and slowing down the rise of water in OSB. There was also verified if application of surface finishes only on the cutting edges could significantly affect the penetration of water into the OSB board. Some of used test methods were based on European technical standards, but were modified in order to determine influence of surface finishes in the long term. Alternative test method was also designed and implemented. The essence of this test method was to determine how high the water can rise in OSB. The research covered 8 different types of surface finishes available on the market. The selected finishes did not require any special treatments to be applied to the surface of the OSB itself. Based on the results, a mutual comparison and evaluation of their effects was carried out.

Evaluation of technical conditions of the object
Majtánová, Romana Viktória ; Láník, Jaromír (referee) ; Schmid, Pavel (advisor)
This work deals with construction material research office building with eighteen floors to the street Šumavská 35 in Brno with ground plan dimensions of about 25 x 25 m. The structure consists of a reinforced concrete substructure and floors of steel frame. The scope of the survey will determine the quality of concrete in vertical supporting columns at level 1. PP structures using cores and subsequent laboratory testing. Another task will be to verify the status of moorings steel perimeter columns to the building of reinforced concrete pillars at the boundary of 1st basement and 1st floor.

Complex diagnostics static structural condition of the building
Voltr, Vojtěch ; Rozsypalová, Iva (referee) ; Schmid, Pavel (advisor)
This diploma thesis deals with the problems of revitalization of historical objects. The theoretical part describes the technologies for static reinforcing and rehabilitation of vertical and horizontal bearing structures for a purpose of increasing the general stiffness of the object. As the practical part a static design project is made for reinforcing of the bearing walls and also for the general reconstruction of the slab. The slab is designed as the composite timber-concrete structure. The design project of the slab is economically compared with other variants. The designs are made for an existing object of the old restaurant in the village Velichovky.

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.

Complex diagnostics of the family house
Tomanová, Jana ; Balkanský, Ondřej (referee) ; Schmid, Pavel (advisor)
This master´s thesis deals with the issue of the building from a clay. It is focused on defects and rehabilitations of these constructions. The introductory parts concerns with probable defects especially of clay buildings, furthermore with causes of the creation of defects, its depictions and the relevance. In the following part the methods of rehabilitation not only of clay buildings are presented. In this part the rehabilitative methods of foundation, vertical and wood constructions, which create mainly the structural support of the buildings, are described. In the second part, the structural and technical research of the current structure with farm part – barn is executed. The part of research is creation of the drawing documentation, description of disposition and structural and constructional solution of building, structural calculation of a part of construction, assessment of actual state of structure and prospective plan of proceeding and rehabilitation.

Buildings monitoring
Kopuletá, Jitka ; Žítt, Petr (referee) ; Schmid, Pavel (advisor)
The bachelor thesis is aimed at the passportization of the breakdowns and imperfections on the front facades of houses on Arne Nováka and Gorkého streets in Brno where the reconstruction of the area of Philosophical Faculty of the Masaryk University will be in progress. The first visual inspection was accomplished before the beginning of the construction works. On its base the monitoring sheets of the separate buildings have been compiled.
