A vector form intrinsic finite element method ( plane frame element ) is developed and applied to study the dynamic responses of offshore template platform under wave force. The horziontal, vertical and rotational motions at each node in the finite element model also were analyzed by the developed solution procedure of offshore structures. Besides, this paper also discussed the application of viscoelastic dampers on the offshore structures. A design for the dampers incorporated in the template structure were presented, and dynamic analyses were carried out to observe the effect of the vibration mitigation on the structures .

A materially non-linear layered beam super element is developed for the analysis of RC beams and columns strengthened by externally bonded steel/FRP plates. The elasto-plastic behavior of RC member is incorporated by its internally generated or externally supplied moment-curvature diagram. The steel plate is assumed to be elasto-plastic and the FRP laminate is assumed to behave linearly elastic up to rupture. The thin epoxy layer between the RC member and the externally bonded lamina is simulated by a special interface element which allows for the changing failure modes from steel plate yielding/FRP plate rupture to separation of the bonded plates as a result of bond failure in the epoxy layer. An empirical failure criterion based on test results is used for the epoxy material of the interface. The most critical aspect of such applications in real life frame structures is the anchorage conditions at the member ends and junctions. This has direct influence on the success and the effectiveness of the application. Therefore, a special corner piece anchorage element is also considered in the formulation of the joint super element, which establishes the fixity and continuity conditions at the member ends and the joints.

>Magister Scientiae - MSc / This dissertation is a presentation to generalize boundedness and pseudocompactness in pointfree topology. We rst obtain and introduce a boundedness notion for elements of a frame. This is then further inspiration to introduce a de nition of bounded frame homomorphism whose domain may be any frame E, not just the frame of open sets of the reals.

Materially non-linear analysis of reinforced concrete frame structures with infill walls requires appropriate mathematical models to be adopted for the beams and the columns as well as the infill walls. This study presents a mathematical model for frame elements based on a 3D Hermitian beam/column finite element and an equivalent strut model for the infill walls. The spread-of-plasticity approach is employed to model the material nonlinearity of the frame elements. The cross-section of the frame element is divided into triangular sub regions to evaluate the stiffness properties and the response of the element cross-section. By the help of the triangles spread over the actual area of the section, the bi-axial bending and the axial deformations are coupled in the inelastic range. A frame super-element is also formed by combining a number of frame finite elements. Two identical compression-only diagonal struts are used for modeling the infill. The equivalent geometric and material properties of the struts are determined from the geometry of the infill and the strength of the masonry units A computer code is developed using the object-oriented design paradigm and the models are implemented into this code. Efficiency and the effectiveness of the models are investigated for various cases by comparing the numerical response predictions produced by the program with those obtained from experimental studies.

本論文旨在探討近義詞的相關議題，特別是要檢視其背後的概念結構與表層的語法功能。透過「方便」與「便利」的研究，本文就這對近義詞在語意上的差異做深入並有系統地分析，並期以此解釋他們在語法層次上不同的表現。 　　以框架語意學(Frame Semantics)為理論架構，本研究發現近義詞「方便」與「便利」會引導出「方便框架」(CONVENIENCE frame)與「不方便框架」 (INCONVENIENCE frame)，而這兩個語意框架雖有相對應的框架成分(frame element)，實質上卻是引發出不同的概念型態。近一步說明這對近義詞在語意上的差別，「方便」與「便利」對於他們所涉入的複雜事件(complex event)持不同的觀點：「方便」主要是專注在結果次事件(result-subevent)並採受恩者(BENEFICIARY)的觀點；而「便利」則較專注在原因次事件(cause-subevent)並採動作者/施恩者(AGENT/BENEFACTOR)的觀點。此外，由於「方便」與「便利」具備了正面、值得嚮往的特質，這也解釋了何以「方便框架」比「不方便框架」有更高程度的目的性(intentionality)。 　　為檢視近義詞在概念上的差異是否會反映於在他們的語法表現上，本研究闡明了「方便」與「便利」的語法功能及其使用分布的情況、以及參與角色(participant role)的凸顯類型(profiling pattern)。結果顯示「方便」與「便利」主要有五種語法功能，即名詞化、修飾名詞、修飾動詞、不及物動詞謂語、及物動詞謂語，最常使用的語法功能為名詞化與動詞謂語(包含及物與不及物)。此五種語法功能皆會突顯某些參與角色，但主要都是突顯了「目的」(PURPOSE)與「手段」(MEANS)；而其他參與角色也會在不同語法功能的使用中被突顯，並且這些突顯類型皆可由「方便」與「便利」在概念上的差異來做解釋。 　　總結來說，本論文闡釋了近義詞「方便」與「便利」在概念上不同的偏好會導致他們在語法上有不同的表現；此外，「方便」與「便利」在參與角色的凸顯類型上亦不相同，這說明了，「方便」與「便利」是屬於不同的構式(construction)。最後，本論文也再次確認了詞彙背後的語意概念會決定其語法的表現。 / The purpose of this thesis is to approach the issue of near-synonyms via the examination of their respective underlying conceptual structures and surface syntactic functions. Specifically, the present study aims to furnish a fine-grained and systematic analysis of the semantic differences between the near-synonymous pair fangbian and bianli that shall better explain their differential syntactic behaviors. 　　Based on the theoretical framework of Frame Semantics, this study found that the conceptual structures of fangbian and bianli are associated with the frames of CONVENIENCE and INCONVENIENCE. While pertaining to a corresponding set of frame elements, the two frames actually prompt distinct conceptualizations. Precisely, fangbian and bianli differ in their perspectivization of the complex event involved: fangbian focuses on the result-subevent and takes the BENEFICIARY’s perspective whereas bianli on the cause-subevent and takes the AGENT/BENEFACTOR’s perspective. In addition, the fact that convenience is desirable and thus typically intended also explains the stronger intentionality involved in the CONVENIENCE frame than in the INCONVENIENCE frame. 　　To investigate whether conceptual differences between the near-synonyms would be manifested in their syntactic behaviors, this thesis further elucidated the syntactic functions and their distribution of fangbian and bianli as well as the profiling of the participant roles in each syntactic function. In particular, five main syntactic functions of fangbian and bianli were identified: nominalization, nominal modifier, verbal modifier, intransitive verbal predicate and transitive verbal predicate; each serves to profile distinct participant roles, mostly PURPOSE or MEANS. Moreover, the profiling of other participant roles can be accounted for by the perspectival distinction between the near-synonymous pair. Finally, the distribution of syntactic functions of fangbian and bianli demonstrated that the usage of the near-synonyms as verbal predicate and nominalization is the most dominant categories. 　　To conclude, this thesis has shown that the conceptual preferences of fangbian and bianli in terms of their perspectivization lead to their different syntactic behaviors. Moreover, the near-synonymous pair also differs in their profiling of the participant roles; in other words, they display distinct profiling patterns and therefore pertain to different constructions. Finally, it still holds for the present study that the semantics of a word drives its syntactic behaviors.
