There are many types of lateral structural resisting systems (framed system, braced system, shear wall system, Tube system, core system, etc), which are basically based on structural subsystem. There are three primary types of 2D or 3D vertical subsystems in buildings (1) Wall subsystems; (2) Vertical Shafts; and (3) Rigid Beam-Column frame. Wall are very rigid subsystem in their plane and may be made up of solid concrete panel, braced timber, steel trusses, and so on. Shafts are stiff 3-D tube structures and are usually made up of four solid or trussed walls for ventilation and services. they can carry vertical loads and serve as excellent horizontal-force resisting elements. they also have some problems, which are space planning inflexibility, disagree between horizontal stiffness center and inertia center, construction problems and soon. Rigid-frame subsystems are very good for space planning flexibility, but vertical resisting stiffness is very small. This study is a structural model analysis for rigid frame with P.C panel to increase lateral stiffness for rigid-frame subsystem. we modeled exterior spandrel beam bolted with P.C panel which is acting as shear wall action. The analysis results showed vertical stiffness increasement. if we apply this method to rigid-frame at inter and exterior wall, we can esealy large increament of the lateral stiffness of the rigid-frame.

The results of this analysis indicate the followings; 1)The multipurpose space, multipurpose hall and audio-visual room in resent years is organized at almost schools. 2)The area of multipurpose space is 40㎡-50㎡ per and their depth os gradually increasing over 6m. 3)The multipurpose space which are located parallel to each classroom and separated by movable partition is most common type in modernized elementary schools.
This study is to investigate rheological properties (slumping behavior & segregation-resistibility) of lightweight concrete and present fundamental data for mixing design of lightweight concrete. As a result of this study, it is suggested that slump target for quality control of fresh lightweight concrete will be set up differently from normal concrete. Because, unit weight of lightweight concrete is much smaller than normal concrete, though rheological constants(yield value) of NC is the same as LC's, these slump values are very different. And, segregation-resistibility can analysis as quantitatively taking advantage of unit weight of all-lightweight concrete. lightweight concrete using ultra lightweight egg. showed segregation when the slump is more than 20㎝, also the more quantity of paste have, the movement of aggregates cover a wide range.
Little has been known about the characteristics of short-term and long-term resettlements on soft clay, such as elastic behaviour and secondary compression due to partial removal of preloading. In this study, different types of oedometer tests on a natural soft clay were peformed for examining such characteristics. As the results of the experiments, the characteristics of short-term and long-term resettlements such as rebound ratio, resettlement point and rate of secondary compression depends on the overconsolidation ratio(OCR) and preloading time. It is showed that resettlement point increased with increasing preloading, but such is not for rebound ratio and rate of secondary compression. This reason would be due to rearrangement of clay particles. And rebound ratio and resettlement point increased with increasing the OCR, but such is not for rate of secondary compression. The correlations between them is showed all the linear relations in a semi-logarithem or log-log plots, and then can be used for settlement prediction in field, as well its results can be compared with those of conventional method. from the comparative results of settlement prediction, it is found as follows : The amount of rebound due to partial removal of preloading and resettlement due to reloading are similar for both methods. But the amount of secondary compression due to partial removal of preloading by this correlation is rather overestimated than that of conventional method, because it would be underestimated the duration of primary consolidation. And for different loading histories, the compression is affected by strain rate(ε_(v)), that is, the compression increases with decreasing strain rate.
The ultrasonic logging method is one of the earliest methods of checking the integrity of pile. The main purpose of the paper is to conduct the model test in water to qualify the ultrasonic analyser, UMQA4, in its accuracy and repeatability and to offer basic information for effective analysis with the field data by model testing of the scaled concrete pile, and thus to increase the applicability of the apparatus. The result of experiment shows that the system is stable and excellent in repetition; and relatively easy and rapid in locating any defects in the pile in vertical section, but not in horizontal one, which should be studied further by tomography, etc. Also, further study on model-test should be done for its applicability to classifying near-surface rock mass features.
To examine lateral earth pressure against fixed wall due to geometry of backfill, a model test was carried out. Soil box (180×75×80mm), 2-directional load cell and rainer were made for this test. And Sumjin river sand as backfill materal was placed in the backfill space with different geometries and relative densities. This test result was compared with the extended Silo theory(Chung et at, 1997) and Jaky's lateral pressure at rest. The comparative results are as follows : When the bottom width between the model wall and the stable slope is narrow, the experimental pressure agree well with that of the extended theory, independent of inclinations of wall and stable slope. However, when the width is not narrow, ie, when Bc/H is larger then 0.333, the experimental pressure is preferably close to the Jaky's lateral pressure at rest. The angle of wall friction have an important effet on the experimental lateral pressure, as wall as bottom width. The wall friction angle was measured the peak at lower placing height, and just after that the value is roughly constant up to the residual state.
A method of architectural formalism focused on collaborative work is presented through semiotic logic in the discourse of architectural communications, which can be a framework for architectural design groupware. Based on the repetitive synchronous and asynchronous process. its unique communicational characteristics of design collaboration through network were considered to make an adequate and realizable tool for architectural design.

This study is about experiment on traditional method using soil to create compressed soil brick. The soil needs water to develop fluidity in the field in different from the hydraulic cement, which cause the drying shrinkage definitely. So, the development of the soil as dry materials is more suitable than the mortar in the field. As a result, compressed soil brick using alginic acid is strong against compressure, and little deflection against drying shrinkage. So, we consider that it is possible to be used in the field as construction materials.
Urban management and C.B.D continuance's problem as a result of the extension of the city area and the existing commercial area's shrink due to city spatial structure lead to a lot of problems including doughnut phenomenon. The purpose of the this study is to figure out ways toward the strategies of commercial area prosperity that acts up positively to the multiple C.B.D by the change of urban spatial structure. The strategies of the commercial area prosperity in existing C.B.D were presented by dividing the recover of city function and the self-efforts for shopping facilities. To recover city function, first is to secure a settled population in hinterland. Second is to extend and complete of C.B.D function. Third is to improve that attractive element of C.B.D
