Experimental Test on Coner Rigid Joint Connection Method for Underground Roadway Structure

Study on Design Method of Joint Panels for Hybrid Railway Rigid-frame Bridges

Fibrous structure and connection surrounding the metacarpophalangeal joint.

The fibrous components of the metacarpophalangeal (MP) joint including the palmar plate, the collateral ligament and the dorsal plate were studied with particular attention paid to the fibrous structure of the fibrous tendon sheath and the deep transverse metacarpal ligament. The tough fibrillar structure around the MP joint, especially the force nucleus, consisted of three types of mixed fiber...

The Method of Model Approximation for the Analysis of Semi-rigid Connection with Parameter Correlation

Abstract: The moment-rotation model is the main study of semi-rigid connection, moreover, the sensitivity coefficients of parameters on semi-rigid connection are the precondition of a moment-rotation model. There are two issues in the current research: the defective models would be obtained without considering the correlation among the parameters of the structure; for the higher precision sensi...

Effects of Semi-Rigid Connection on Structural Responses

There are several idealizations in numerical analysis of structures. In the joints and supports, which is usually assumed to be pinned or rigid, semi-rigid connection should be considered to obtain more realistic, reliable and also economical results. In this study, rotational spring stiffness-connection ratio relation is clearly explained and revealed. A finite element program SEMIFEM is devel...

A Rigid Irregular Connection on the Projective Line

In this paper we construct a connection ∇ on the trivial G-bundle on P for any simple complex algebraic group G, which is regular outside of the points 0 and ∞, has a regular singularity at the point 0, with principal unipotent monodromy, and has an irregular singularity at the point ∞, with slope 1/h, the reciprocal of the Coxeter number of G. The connection ∇, which admits the structure of an...
