Previous finite element studies have shown that AASHTO Standard load distribution factor (LDF) equations appear to be conservative for longer spans and larger girder spacing, but too permissible for short spans and girder spacing. AASHTO LRFD specification defines the distribution factor equation for girder spacing, span length, slab thickness, and longitudinal stiffness. However, this equation requires an iterative procedure to correctly determine the LDF value due to an initially unknown longitudinal stiffness parameter. This study presents a simplified LDF equation for interior and exterior girders of two-span continuous I-girder bridges that does not require an iterative design procedure. The finite element method was used to investigate the effect of girder spacing, span length, slab thickness, slab width, and spacing and size of bracing. The computer program, GTSTRUDL, was used to idealize the bridge superstructures as the eccentric beam model, the concrete slab by quadrilateral shell elements, steel girders by space frame members, and the composite action between these elements by rigid links. The distribution factors obtained from these analyses were compared with those from the AASHTO Standard and LRFD methods. It was observed through the parametric studies that girder spacing, span length, and slab thickness were the dominant parameters compared with others. The LRFD distribution factor for the interior girder was found to be conservative in most cases, whereas the factor for the exterior girder to be unconservative in longer spans. Furthermore, a regression analysis was performed to develop simplified LDF formulas. The formulas developed in this study produced LDF values that are always conservative to those from the finite element method and are generally smaller than the LDF values obtained from the AASHTO LRFD specification. The proposed simplified equation will assist bridge engineers in predicting the actual LDF in two-span continuous I-girder bridges.

The load distribution factor (LDF) values of simplified composite H beam panel bridges (SCHPBs) that were subjected to one lane and two lane loads were investigated using three dimensional finite element analyses with the computer program ABAQUS (2007). This study considered some design parameters such as the slab thickness, the steel plate thickness, the span length, and the continuity of the SCHPBs in the development of new LDFs. The distribution values that were obtained from these analyses were compared with those from the AASHTO Standard, LRFD, and the equations presented by Tarhini and Frederick, Huo et al., Back and Shin, and Cai. The AASHTO Standard distribution factors for SCHPBs were found to be very conservative. Sometimes, the distribution values from the finite element analyses for interior girders were similar to the results of the AASHTO LRFD, whereas the values for exterior girders were conservative in most cases. The new distribution values that were presented in this study produced LDFs that are more conservative than those from the finite element method. For the simple application of the design to SCHPBs, bridge engineers can use 0.42 for the interior girder and 0.32 for the exterior girder. The proposed values improve the current design procedure for the LDF problem and increase SCHPB design efficiency.

On the basis of the strain-based shear strength model developed in the previous study, a strength model was developed to predict the direct punching shear capacity and unbalanced moment-carrying capacity of interior and exterior slab-column connections. Since the connections are severely damaged by flexural cracking, punching shear was assumed to be resisted mainly by the compression zone of the slab critical section. Considering the interaction with the compressive normal stress developed by the flexural moment, the shear strength of the compression zone was derived on the basis of the material failure criteria of concrete subjected to multiple stresses. As a result, shear capacity of the critical section was defined according to the degree of flexural damage. Since the exterior slab-column connections have unsymmertical critical sections, the unbalanced moment-carrying capacity was defined according to the direction of unbalanced moment. The proposed strength model was applied to existing test specimens. The results showed that the proposed method predicted the strengths of the test specimens better than current design methods.

The purpose of this study was to categorize the decorative characteristics of the Rococo Age, which displays the most glamorous and elegant decorative beauty, in architecture, interior decorations, paintings, and patterns, and to analyze these characteristics and graft them onto art masks in a modern way. Piece I is a mixed media piece that based its motif on the ceilings and pulpits of the German Vis Pilgrimage Church, which is representative architecture of the Rococo Age. It was glamorously produced using gold and cubic zirconia. Piece II is also a mixed media piece that borrowed its motif from the exterior and gazebo of the Sanssouci Palace in Germany, another representative piece of architecture from the Rococo Age, and it was produced to clearly display the image of the Sanssouci Palace, using emerald and ivory. Piece III applies the furniture trends of the Rococo Age. Curves in S and C shapes, which can often be found in Chinese furniture, along with dark backgrounds, common in portrait paintings, were applied to give a sense of weight and dignity. Piece IV is an application of the fabric patterns of the Rococo Age. Continuous patterns of flowers and greenery stems were drawn on the mask to recreate the fabric patterns of the age. Piece V used the painting 'Swing' of the Rococo Age as its inspiration. Lace and ribbon decorations were used to emphasize feminine beauty and express the loveliness of the woman that appears in the painting. Piece VI borrows from the painting 'Madame de Pompadour' of the Rococo Age and the clothing worn by Pompadour. This piece grafted colors and themes through the painting and expressed a fusion of the dresses of Pompadour and lace that is clearly displayed in the architecture, paintings, clothing, interior decorations, and patterns of the Rococo Age, along with the rocaille (asymmetrically shaped decorations that resemble clams), flowers, leaves, stems, and Chinoiserie styles. These motifs clearly display the decorative characteristics of the age and these were grafted them onto art masks, confirming that it is possible to create new designs.

This research began by considering that, although architecture and architectural culture of the last two decades seem to have rediscovered ornament and some recent studies have reconsidered the ornamental issues of contemporary buildings, there is currently some difficulty in providing a synthetic investigation of this topic, because of the complex nature of the contemporary architectural situation. Following this premise, this research provides some reference points for further studies that will aim to expand the understanding, and attempt to classify and hypothesize the future of contemporary ornamental phenomena. Based on the assumption of the historical continuity of ornamental problems, and adopting the relation - both technical and aesthetic - between ornament and structure as one of the crucial issues to link past and present problems, the study firstly defines two categories and two sub-categories concerning the relation between ornament and structure, namely: a) ornament integral with the structure and b) ornament applied to the structure; a1) ornament visually expressing the structure and a2) ornament not visually expressing the structure. The study then reviews the historical development of ornament from ancient times to the present in the light of the above mentioned categories, and finally discusses the principles of traditional and modern ornament thus analyzed in relation to contemporary ornamental trends, as identified in selected case studies. Some common points between past and contemporary experiences are revealed in order to facilitate further investigations. In particular, the analysis shows a certain trend in contemporary architecture for a strong link between ornamental treatment and the structure of the building and a current tendency among contemporary designers to keep the exterior appearance of the building project separate from the design of the rest of the construction.

Laboratory buildings with specialized equipment and ventilation systems pose challenges in terms of efficient energy use and initial construction costs. Additionally, lab spaces should have flexible and efficient layouts and provide a comfortable indoor research environment. Therefore, this study aims to identify the correlation between the facade of a building and its interior layout from case studies of energy-efficient research labs and to propose passive energy design strategies for the establishment of an optimal research environment. The case studies in this paper were selected from the American Institute of Architects Committee on the Environment Top Ten Projects and Leadership in Energy and Environmental Design (LEED) certified research lab projects. In this paper, the passive design strategies of space zoning, façade design devices to control heating and cooling loads were analyzed. Additionally, the relationships between these strategies and the interior lab layouts, lab support spaces, offices, and circulation areas were examined. The following four conclusions were drawn from the analysis of various cases: 1) space zoning for grouping areas with similar energy requirements is performed to concentrate similar heating and cooling demands to simplify the HVAC loads. 2) Public areas such as corridor, atrium, or courtyard can serve as buffer zones that employ passive solar design to minimize the mechanical energy load. 3) A balanced window-to-wall ratio (WWR), exterior shading devices, and natural ventilation systems are applied according to the space programming energy requirements to minimize the dependence on mechanical service. 4) Lastly, typical laboratory space zoning categories can be revised, reversed, and even reconfigured to minimize the energy load and adjust to the site context. This study can provide deep insights into various design strategies employed for construction of green laboratories along with intuitive arrangement of various building components such as laboratory spaces, lab support spaces, office spaces, and common public areas. The key findings of this study can contribute towards creating improved designs of laboratory facilities with reduced carbon footprint and greenhouse emissions.

The purpose of this study is to reveal the space composition of fireplace and common features of both Prairie and Usonian House found within Wingspread House. This house is the last and largest Prairie house and zoned house built in a Usonian period. However, this house is not an independent work, but rather Wright's evolutionary experiments of fireplace from his early works and his pursuit of Usonian ideal. This paper can be summarized as follows: 1) Living room has been transformed to allow spatial continuity towards exterior view and access and between neighboring rooms by removing doors and inglenook. At the Wingspread house Wright has introduced a freestanding fireplace in a living room with higher and prominent roof structure, therefore the space became a focal point as well as the central space of the entire house. 2) Wingspread and Coonley house have gallery space in common, but they have different settings in the living room composition. Also the living room and gallery space of Wingspread and Usonian houses have prospect and refuge principle by expansion and compression. 3) Wingspread house is a successful combination of Prairie and Usonian style to meet client's requirements in space composition and Wright's technology and economical experiments. This study is intended to reevaluate the significance of this house bridging his two great residential periods.
