Generalized Finite Difference Method In Elastodynamics Using Perfectly Matched Layer

Korkut, Fuat 01 July 2012 (has links) (PDF)
This study deals with the use of the generalized finite difference method (GFDM) in perfectly matched layer (PML) analysis of the problems in wave mechanics, in particular, in elastodynamics. It is known that PML plays the role of an absorbing layer, for an unbounded domain, eliminating reflections of waves for all directions of incidence and frequencies. The study is initiated for purpose of detecting any possible advantages of using GFDM in PML analysis: GFDM is a meshless method suitable for any geometry of the domain, handling the boundary conditions properly and having an easy implementation for PML analysis. In the study, first, a bounded 2D fictitious plane strain problem is solved by GFDM to determine its appropriate parameters (weighting function, radius of influence, etc.). Then, a 1D semi-infinite rod on elastic foundation is considered to estimate PML parameters for GFDM. Finally, the proposed procedure, that is, the use of GFDM in PML analysis, is assessed by considering the compliance functions (in frequency domain) of surface and embedded rigid strip foundations. The surface foundation is assumed to be supported by three types of soil medium: rigid strip foundation on half space (HS), on soil layer overlying rigid bedrock, and on soil layer overlying HS. For the embedded rigid strip foundation, the supporting soil medium is taken as HS. In addition of frequency space analyses stated above, the direct time domain analysis is also performed for the reaction forces of rigid strip foundation over HS. The results of GFDM for both frequency and time spaces are compared with those of finite element method (FEM) with PML and boundary element method (BEM), when possible, also with those of other studies. The excellent matches observed in the results show the reliability of the proposed procedure in PML analysis (that is, of using GFDM in PML analysis).

Сравнительный анализ возведения ленточного и свайного фундаментов гражданского здания : магистерская диссертация / Comparative analysis of the construction of strip and pile foundations of a civil building

Чжао, Ж., Zhao, R. January 2023 (has links)
В работе выполнен сравнительный анализ свайных и ленточных фундаментов гражданского здания. Сравнение выполнено по стоимости и трудоемкости изготовления фундаментов для определенных инженерно-геологических условий с учетом действующих нагрузок. / The work performed a comparative analysis of pile and strip foundations of a civil building. The comparison was made based on the cost and labor intensity of manufacturing foundations for certain engineering-geological conditions, taking into account the existing loads.

Nosná konstrukce polyfunkčního domu / Load bearing structure of multifunctional house

Martínek, David January 2018 (has links)
Master´s thesis is based on analysis and design of a load-bearing structure of multifunctional house. The main load-bearing elements in the vertical direction are the monolithic reinforced walls and the main load-bearing elements in the horizontal direction are monolithic reinforced concrete plates. The connection of individual floors is made of monolithic reinforced concrete staircases. The foundation of the building is realized through a system of strips foundation. Design drawings are made to selected elements of the structure.

Polyfunkční dům Lignum / Multifunctional house Lignum

Jakubčánin, Marek January 2015 (has links)
The diploma thesis focuses on a mixed-use building with a rectangle-shaped ground plan in Žilina city. The object is four-storey and with no basement. It is split into two sections. The first one provides a space for three operations in northeastern part of the first floor with an attached parking lot. These operations are not further described in this project and depending on investor´s requirements some changes may apply. The second part is an apartment housing section. The first floor contains utility rooms such as storage and buggy room. The housing sections are accessible with two entrances. The apartments are located from the second up to the fourth storey and are designed 1+KK, 2+KK,3+KK and 4+KK respectively. The apartments are assigned with parking spaces isolated from operations parking lot. Vertical bearing walls are made of clay blocks POROTHERM 30 AKU P+D, which are used also as internal bearing party. Internal bearing walls placed in apartments are made POROTHERM 25 AKU P+D and completed by POROTHERM 14 PROFI P+D. Walls will be placed on conrete and reinforced concrete strip foundation. Building has external thermal insulation made by EPS gray 200mm thick. Horizontal load-bearing structures are made by reinforced concrete. Object has flat roof with minimum slope 3%. Damp proof is made by PVC-P membrane. As thermal insulation is used mineral wool.

Stanice technické kontroly / Technical inspection station

Smolík, Jindřich January 2013 (has links)
This thesis deals with a new building technical control station, office space and hotel. The building is situated on three floors, on the first floor we find technical inspection station and office premises manual technical lines. On the second floor there are offices. On the third there is a hotel. The building is designed by a rectangular shape with a flat roof and on the third floor there is a trafficable terrace. The supporting structure consists masonry Porotherm and reinforced concrete system columns, which is found only on the first floor. The supporting structure of tensioned ceiling consists of prestressed beams ceilings Spiroll a concrete slab. External surface finish on the first floor is made up of silicate plaster paste and the remaining two floors are made of ventilated facades. Utility room is located on the first floor, from where a chimney Schiedel is build. Most of the floor space in the building are made of a carpet or tiles, only in the service line is epoxy coating
