The required connection ductility has been evaluated, considering geometric, material and connection nonlinearity, for 6-story unbraced and 20-story braced steel structures subjected to ultimate lateral load. For material nonlinearity, section moment-curvature relationship and member stiffness matrix have been derived utilizing fiber model and linear flexibility distribution model. In 6-story structure with semi-rigid connections for rigid connection, the required connection ductility is less than that for rigid connection. In 20-story structure, the required connection ductility for semi-rigid connection is almost the same as that for shear connection and the required ductility for rigid connection is larger than that for semi-rigid or shear connection.

Leslie Marmon Silko's Storyteller does not belong to a typical category of books, for it looks more like a family album with photographs, poems and Pueblo narratives as well as short stories authored by her. This 'book' without any chapters defies a traditional concept of books we are familiar with. In addition to refusing to be labelled as a conventional book, I argue, Storyteller defies the tradition of Western personal writing in that it shows the collective power of stories. That is, stories have the collective power which is impersonal beyond personal, internalized identity. It does not mean, however, the collective power comes from groups rather than individuals. It is not the conventional opposition of group and individual but that of group and collectiveness that matters here. I draw a distinction between group and collectiveness on the ground that the former actually groups individuals into categories with which individuals identify themselves. It is not group but collectiveness where stories find their power. "Storyteller," the first of eight short stories in the book, tells the story of an unnamed protagonist, a Yupik Eskimo girl, who takes revenge of her parents who died after drinking poisoned alcohol sold by a white storeman. There are four layers of stories in this short story. The first one is the old man's story of a blue glacier bear; the second one is a revenge story of the Yupik girl; the third one is a story told by the girl to the attorney after being arrested for the death of a storeman. And the final one is the story told to us by Silko, entitled "Storyteller." Although the structure of story within story resembles a technique of metafiction at a glance, it surely is a characteristic of Pueblo narratives in general, according to Silko. This kind of stories within stories refers to the collective power of story which, like a spider's web with many little threads radiating from the center and crisscrossing one another, is also a characteristic of stories on the Web today.

The essay explores the narrative structure of the classical Chinese feature animation, (a.k.a. Da Nao Tian Gong, 1964). The film is presented with a modular structure which is quite unique compared with the storytelling in feature animated films from other cultures, but could be connected with the tradition narrative structure in Chinese Zhanghui style novels in Ming and Qing Dynasty. By relating the original text of the story, the 16th century novel Journey to the West (a.k.a. Xi You Ji), with the film , the essay addresses the question of how the narrative tradition in Chinese classical literature influenced the Uproar in Heave for its segment narrative structure, character driven storytelling strategy and mirrored repetitive 2 plot lines. The subject of this essay is even more significant after the restored 3D version of was re-released in the spring of 2012 and became one of the best-selling animated feature film in the history of the country.

I started this study to solve the doubt about actual condition of Oksosun stories. which was recorded in Cheonyerok(天倪錄) is the first form of Oksosun stories. But this story seems a very outstanding work. had a structure of romance. The hero's character was a romantic figure but Oksosun's character was a figure of Yadam. Afterward recorded in Gyeseoyadam(溪西野譚) and recorded in Cheongguyadam(靑邱野談) took place changes in the structure of the story. A lot of narrative paragraphs were removed in these stories. So and achieved the typical structure of Yadam. In recorded in Dongyahwijip(東野彙輯), the change of style was caused once more. So we can see the transmitting and changing flow of Yadam by this study; Romantic Yadam ${\rightarrow}$Typical Yadam , ${\rightarrow}$Noverized Yadam .

In the last decades, valuable results have been reported regarding conventional passive, active, semi-active, and hybrid structural control systems on two-dimensional and a few three-dimensional shear buildings. In this research, using a three-dimensional finite element model of high-rise concrete structures, designed by performance based plastic design method, it was attempted to construct a relatively close to reality model of concrete structures equipped with Tuned Mass Damper (TMD) by considering the effect of soil-structure interaction (SSI), torsion effect, hysteresis behavior and cracking effect of concrete. In contrast to previous studies which have focused mainly on linearly designed structures, in this study, using performance-based plastic design (PBPD) design approach, nonlinear behavior of the structures was considered from the beginning of the design stage. Inelastic time history analysis on a detailed model of twenty-story concrete structure was performed under a far-field ground motion record set. The seismic responses of the structure by considering SSI effect are studied by eight main objective functions that are related to the performance of the structure, containing: lateral displacement, acceleration, inter-story drift, plastic energy dissipation, shear force, number of plastic hinges, local plastic energy and rotation of plastic hinges. The tuning problem of TMD based on tuned mass spectra is set by considering five of the eight previously described functions. Results reveal that the structural damage distribution range is retracted and inter-story drift distribution in height of the structure is more uniform. It is strongly suggested to consider the effect of SSI in structural design and analysis.

The purpose of this study was to investigate the relationship between age, internal state information, and narrative structure. Another purpose was to examine how the kinds of replica play and story props affect the theme of children's narratives. The subjects were 36 4-and 5-year-olds. Children's narratives were audiotaped and analyzed accordmg to narrative structure, themes and internal state factors. The results indicated that 5-year-olds showed well organized narrative structure such as a descriptive narrative and a primary plotted narrative whereas 4-year-old presented no response and a descriptive narrative. Also, 5-year-olds used more internal state information in the narratives than 4-year-olds. The replica figures serve to remind the chiidren of story themes: the children with police props presented negative themes while children with playground props showed positive themes.

This study investigated the effect of soil-structure interaction (SSI) on the response of base-isolated buildings. Seismic isolation can significantly reduce the induced seismic loads on a relatively stiff building by introducing flexibility at its base and avoiding resonance with the predominant frequencies of common earthquakes. To provide a better understanding of the movement behavior of multi-story structures during earthquakes, this study analyzed the dynamic behavior of multi-story structures with high damping rubber bearing (HDRB) behavior base isolation systems that were built on soft soil. Various models were developed, both with and without consideration of SSI. Both the superstructure and soil were modeled linearly, but HDRB was modeled non-linearly. The behavior of the specified models under dynamic loads was analyzed using SAP2000 computer software. Erzincan, Marmara and Duzce Earthquakes were chosen as the ground motions. Following the analysis, the displacements, base shear forces, top story accelerations, base level accelerations, periods and maximum internal forces were compared in isolated and fixed-base structures with and without SSI. The results indicate that soil-structure interaction is an important factor (in terms of earthquakes) to consider in the selection of an appropriate isolator for base-isolated structures on soft soils.

This study analyzed the isolation effect for a 15-story reinforced concrete (RC) building with regard to changes in the beam-column stiffness ratio and the difference in the vibration period between the superstructure and an isolation layer in order to provide basic data that are needed to devise a framework for the design of isolated RC buildings. First, this analytical study proposes to design RC building frames by securing an isolation period that is at least 2.5 times longer than the natural vibration period of a superstructure and configuring a target isolation period that is 3.0 s or longer. To verify the proposed plan, shaking table tests were conducted on a scaled-down model of 15-story RC building installed with laminated rubber bearings. The experimental results indicate that the tested isolated structure, which complied with the proposed conditions, exhibited an almost constant response distribution, verifying that the behavior of the structure improved in terms of usability. The RC building's response to inter-story drift (which causes structural damage) was reduced by about one-third that of a non-isolated structure, thereby confirming that the safety of such a superstructure can be achieved through the building's improved seismic performance.

Horizontal displacement of high-rise building is an essential index for assessing the structural performance and safety. In this paper, a novel inclinometer-based method is proposed to address this issue and an algorithm based on three spline interpolation principle is presented to estimate the horizontal displacement of high-rise buildings. In this method, the whole structure is divided into different elements by different measured points. The story drift angle curve of each element is modeled as a three spline curve. The horizontal displacement can be estimated after integration of the story drift angle curve. A numerical example is designed to verify the proposed method and the result shows this method can effectively estimate the horizontal displacement with high accuracy. After that, this method is applied to a practical slender structure - Shanghai Tower. Nature frequencies identification and deformation monitoring are conducted from the signal of inclinometers. It is concluded that inclinometer-based technology can not only be used for spectrum analysis and modal identification, but also for monitoring deformation of the whole structure. This inclinometer-based technology provides a novel method for future structural health monitoring.

In this paper, the dynamic response of a multi-story steel moment resisting frame equipped with viscoelastic dampers or lead rubber bearing type isolators subjected to seismic loads is investigated analytically. The objective of this study is to find the best location of viscoelastic dampers by the maximum stress method and maximum story drifts method from structure analysis. Also, a secondary objective of the study is to compare the member force, combined stress, and natural period of the structure retrofitted with viscoelastic dampers or lead rubber bearing type isolators to find effective vibration control method.
