The primitives of the vE are subcubes of the cubic frame buffer and are of three kinds: rooms (3D windows), jacks (3D cursors), and figurines (3D ,cons). In addition to manipUlating these primitives, the vE also serves as a monitor for interaction, as an interfaoe for 3D input devices, and as a channel for inputling into the cubic frame buffer 3D voxel images from either 3D scanners or a voxel ...

three dimensioned finite element analysis were conducted on concrete block paving. in order to verify the calculated results, an experimental case study was analyzed. good agreement was observed between the measured and the calculated results. based on the finite element analysis results and available failure models, comprehensive design charts were developed for port and industrial pavement wh...

In order to investigate the seismic performance of prestressed concrete rocking frame (PCRF), a theoretical model based on rigid body is established for one-story single-span PCRF. The PCRF studied in this paper has connecting interfaces set at column feet and inner faces beam–column joints, allowing columns be uplifted with accompanying separation interface rotation beam around interface. tend...

This study investigates the effect of different link beam lengths in the Reinforced Concrete (RC) frame retrofitted with the Linked Column Frame (LCF) system. It also investigates the ratio of the link beam length (e) to the span length of the RC frame (L) from 0 to 1.5 for the 9 models of the RC frame retrofitted by the LCF system has been investigated. In addition, it studies the formation of...

Elevated rail transit has been developed in some big cities in China in recent years. However, specialized codes for design of the bridges in the elevated rail transit system have not yet been established. Based on the prestressed concrete (PC) box girder bridges on Guangzhou metro line 4, some technical features of design principle and technology requisition, ensemble plan and design load of b...

Monitoring the degradation of dynamic elastic modulus (Ed) concrete is great importance to track durability deterioration for hydraulic structures. For aqueduct under investigation in this study, bent frames and moment frame supports (Ed-frame), arch trusses (Ed-arch) shear stiffnesses asphaltic bearings U-shaped flumes (Kflume) are main parameters define behavior structure, which have direct c...

The composite structural system (RCS) is a new type of moment frame, which is including a combination of concrete columns (RC) and steel beams (S). These structural systems have the advantages of both concrete and steel frames [1]. In previous research on composite structures, there are some studies regarding RCS composite conections, but there is no investigation about seismic resisting system...
