The method to form the space of the pneumatic structures by internal pressure is classified greatly as the dual type with the nlty type. The shape of the pneumatic structures consists of the curved surface under uniform tension not greatly to be deformed by the design load and stress must not be concentrated also. Therefore, In this study, we have done the structural analysis of the unity typed pneumatic structures by the NASS which is the program for nonlinear analysis. The analytic model is a rectangular pneumatic membrane structures which have four side fixed edges. And we have done the nonlinear incremental analysis considering the orthotropic material.
A Study on the Shear Resisting Effect of Filling-up Carbon Fiber Rod Plastic in Reinforced Concrete Beam without Web Reinforcement

Journal of the Korean Association for Spatial Structures, volume 5, issue 2, 2005, Pages 57~63
The reinforced concrete becomes deteriorated. In strengthening of reinforced concrete structure, it is recently useing FRP. The purpose of this study is to investigate the shear resisting effort of filling-up CFRP in reinforced concrete beams without web reinforced. Six specimens were manufactured and tested. In the test result, it was analysis. The main variables in the test were a space and volume of CFRP.

The reinforced concrete becomes deteriorated. In strengthening of reinforced concrete structure, it is recently useing FRP. In research, flexural strengthening of reinforced concrete beam can be Efficient design. But shear srengthening og reinforced concrte beam can't be Efficient design by variable cause. The purpose of this study is to investigate the shear resisting effect of filling-up CFRP in reinforced concrete beams with web reinforced. Ten specimens were manufactured and tested. In the test result, it was analysis. The main variables in the test were a space of web reinforcement and a direction of CFRP.

Tensegrity is a relatively new structural system based on the use of continuous tension-discontinuous compression. Of course, a much more detailed structural investigation would be necessary, but at least in order to achieve the intended purpose, it is essential to understand the structural principles and the fundamental forces of tensegrity. Once this point is established, the applications of them to architecture are described, as well as the characteristics of these structures. Then, in spite of the controversial definitions to explain these systems, several examples of tensegrity prototypes or modules constructed in iESD(Institute of Environmental Structure Design) are presented to illustrate the feasibility of tensegrity as a lightweight structure. In this work, consequently, the reformability and application of tensegrity modules have also been researched in architecture, after the patterns of basic module as well as fundamental definition are introduced.

The Space structures may have large freedom in scale and form. And especially Hybrid structures are received much attention from the view points of their light weight and aesthetics. Hybrid systems are stable structures which are reticulated spatial structures composed of compressive straight members, struts and cables and Membranes. In this paper, The Hybrid Unit System are suggested using the Membrane and Cable elements based on the Tensegrity Unit system. Also, The Hybrid System of double-layered single curvature is presented. We analyze the force density method allowing form-finding for Tensegrity systems. And We analyze the shape analysis by the LARSH which is the program for nonlinear analysis.
Prediction of Shear Strength of Reinforced Concrete Beams with High-Strength Steel Bars using Truss Models

As building structures are becoming high-rise, large-scale, and specialized, the use of high-strength materials increase. Therefore, an analytical model is necessary to appropriately predict the shear strength of reinforced concrete (RC) beams with high-strength materials. This study presents a truss model which is able to reasonably predict the shear strength of the RC beams having high-strength steel bars. Test results of 107 RC beams reported in the technical literatures were collected to check the validity of proposed model, TATM, for the shear strength of the RC beams with high-strength reinforcing bars. They were compared to theoretical results obtained from proposed model, TATM, and existing truss models. The experimental results were better predicted by TATM rather than other truss models, and the ratios of experimental results to theoretical results obtained from TATM were almost constant regardless of the yield strengths of tension and shear reinforcements.
