 Main methods to determine subgrade reaction is systemized in this master thesis work. Determination of static and dynamic deformation modulus, when relative soil density is known, are also familiarized. Correlation between the parameters is given in section 2. Experiments were made to prove that there is a link between deformation modulus and surcharge. If surcharge depends linearly from depth, then a function was created to predict deformation modulus values in weak soil when depth varies. 2 similar construction (pipes and tunnels) methods were used to design a buried tank. Design model was created by these design programs: Robot Structural Analysis Pro, SCAD, and PLAXIS 2D. An additional tank modelling method has been suggested by the author. Supports were assigned in plane instead of in a straight line. The updated model seems to better fit for low stiffness construction materials like GRP composites. In these design models all common tank structural elements were included: longitude domes, light and heavy stiffeners, orthotropic material. Main design parameters like virtual elastic modulus, Poisson ratio, creep factor, factor of durability. Results are summarized in conclusions. Suggestions were provided to help future researchers and designers with this kind of problems: structural design of composite polymer structures, design of buried thin-shelled tanks and evaluation of deformation modulus.

 This final master thesis analyses the methods of stabilising the foundation of buildings and the most attention giving for the soil extractio method, wich using have bin stabilised such a historical buildings as Mexican cathedral and Pisa Tower. In the methodical part of this thesis was developed two laboratorical tests to study the reaction of extracted soil under the pressure.The tests was carry out whit 4 types of sandy soils by variating the humidity and pressure. From the received results was made suchlike conclution: 1. By doing the soil exstraction from sandy soils, the soil deformation depends mostly from the humidity and the pressure in the soil. The dry coarse sand deformates the most ant the wett fine sand - the least. 2. This method is not recomendet to use in sandy soils because of the arc efect building in the sandy soils. This method, as the experience shows, can be used in soft fluid clays and organic soils. 3. This labor tests can be used for calculating the soil extraction from in the real field to get the information about soil characteristics during exstraction. Structure: introduction, analytical part, methodical part, conclusions and suggestions, references. Thesis consist of: 75 p. text without appendixes, 68 pictures, 22 tables, 20 bibliographical entries. Appendixes included.

 This masters work purpose is to estimate loadings in construction; calculate foundations dimensions; calculate separate foundations displacements; compare separate foundations displacements between themselves; find relative displacements values and estimate contiguous foundations via geological difference; estimate sand different partical size compression and find primary compression limits when soil is under load; present a report of calculations and laboratory investigations. In this final work was used Businesque problem, summing method and programs: “STAAD.Pro”, “MathCad”, “SCAD”, “AutoCad”, “Exel”. From practical view this work importance is to increase understanding of construction loadings and and factors influence on soil – structure interaction. Calculations of foundations displacements showed that separate foundations and contiguous foundations displacements did not reached their critical magnitudes. Contiguous foundations evaluation to each over could not be accounted then betweeen each over foundation is more than 7,00 m. Sand compression characteristics and sand fraction shape investigation showed that primary compression appears only in first 5 seconds. Because of primary compression all prognosis about total foundation displacement in sand soil estimates when construction is in building period.

 In the master thesis the problems of structure modeling, discretization-optimization and their solution methods and algorithms are analyzed. The original technique for optimization and discretization of beam structures has been suggested; The packages of image algebra methods and of the finite element methods were employed for that. Several packages of finite element method have been reviewed and the most suitable packages for the current problems were identified. The methods for obtaining skeletons of digital images were explored. The algorithms for optimization and discretization of beam structures has been suggested and coded. The program created consents of the part for image processing and input data preparing, and the part for image the finite element via method. The results obtained are represented and verified by STAAD.Pro package. During the discretization, the positions of structure nodes are obtained in the intersection of skeleton segments. The segments' cross-section areas are obtained in the middle-points between two adjacent nodes. The positions of nodes may be corrected if the nodes close to each other. The test-calculation, analysis of results and verification are presented and conclusions are drawn.

 Due to the use of refined ultimate state theories as well as high strength concrete and reinforcement, resulting in longer spans and smaller depths, the serviceability criteria often limits application of modern reinforced concrete (RC) superstructures. In structural analysis, civil engineers can choose between traditional design code methods and numerical techniques. In order to choose a particular calculation method, engineers should be aware of accuracy of differ-ent techniques. Adequate modelling of RC cracking and, particularly, post-cracking behaviour, as one of the major sources of nonlinearity, is the most im-portant and difficult task of deformational analysis. In smeared crack approach dealing with average cracking and strains, post-cracking effects can be modelled by a stress-strain tension-stiffening relationship. Most known tension-stiffening relationships have been derived from test data of shrunk tension or shear mem-bers. Subsequently, these constitutive laws were applied for modelling of bend-ing elements which behaviour differs from test members. Furthermore, such re-lationships were coupled with shrinkage effect. Therefore, present research aims at developing a technique for deriving a free-of-shrinkage tension-stiffening re-lationship using test data of shrunk bending RC members. The main objective of this PhD dissertation is to investigate shrinkage influence on deformations and tension-stiffening of RC members subjected to short-term loading. Present... [to full text]

 Necessary information about soil properties, which is needed for designers and constructors, is obtained in each construction site while examining physical and mechanical properties of soils. Soil strength parameters and using them determined soil bearing resistance usually are defined with some errors. If we know the reasons of errors, disadvantages of testing equipment could be eliminated, methodology of data evaluation could be developed, soil parameters could be determined more precisely and foundation designed more economically. At present triaxial and direct shear tests are the most common tests for determination of soil shear strength parameters in laboratories. Different values of soil shear strength parameters are determined using laboratory equipment of various types. Triaxial test is the most widely used method for determination of soil shear strength parameters. This is one of the most reliable methods to model stress-strain state of ground. It is assumed that soil sample deforms uniformly during the triaxial test. But it is not often the case that a sample in triaxial apparatus deforms uniformly. Questions arise, what is stress-strain distribution in soil sample, when a load is transmitted in a prescribed way? What influence does a non-uniformity have on the soil strength parameters and on foundation size calculated using determined soil strength parameters? Why sandy soil strength parameters obtained from triaxial test are bigger than the one’s, obtained from... [to full text]

 Evaluation of different physical and mechanical factors of concrete according to STR and EC 2 models is considered in this master thesis. Probabilistic model for prestress loss determination is presented in this paper. The analysis of separate and total losses according to STR and EC 2 models was carried out. Some differencies of these models were described. The influence of several factors to the value of separate prestress loss has been studied in this thesis. The probabilistic analysis of long-term losses of post-tensioned RC beam has been carried out. The comparison of total prestress loss values of hollow core slabs according to EC 2, STR and experimental results is subjected in this master thesis.
