Semi-empirical analytical modelling of equivalent dynamic shear strength (EDSS) of rock joint
, 2021 A systematic dynamic triaxial series of tests on replicated rough rock joints were carried out, and results clearly highlight the strength attenuation as a function of joint degradation with respect to the number of loading cycles. A novel semi-empirical

Study on Semi-Rigid Joint Performance and Stability Bearing Capacity of Disc-Type Steel Pipe Support
BuildingsThe current lack of standardized calculation methods for disc-buckle-type steel pipe supports, coupled with unsafe calculation length coefficients, has resulted in frequent safety incidents leading to severe casualties and economic losses. In this paper,

Semi-rigid behaviour of plane timber structures
It is common practice in the analysis of structural frames, to either assume that the joints are pinned or rigid. In fact the real behaviour of a joint is neither pinned nor rigid, and lies somewhere between the pinned and rigid assumption.

The Stability of Elliptic Paraboloid Grid Shell Lighting Roofs with Semi-Rigid Joints
, 2011 Grid shell is a new type of single layer latticed shell. Joint connections of this structrue always adopt semi-rigid joints: in-plane pin joints, out-plane rigid joints.

Parametric Study on Mechanical Behavior of Beam–Column Joint with L-Shaped Components
MetalsThis paper introduces a beam–column joint with an L-shaped component formed by combining two traditional semi-rigid connection methods, namely top and bottom angle steel connections and end-plate connections.

Design of Bionic Knee Joint Mechanism based on Tensegrity Structure
Jixie chuandong, 2020 On the basis of the locomotion mechanism and biological characteristic of the human knee joint，a structural mapping model of bionic knee joint mechanism is established through equivalent mapping and bionic design method which is based on a C4S2 plane ...

Displacement based moment distribution method for semi-rigid frames
In this paper, a fully analytical approach is proposed for framed structures with semi-rigid beam-to-column connections. Traditionally, the analysis of frame structures is based on the assumption that all connections are either frictionless pinned or ...

The effect of semi-rigid joints on the design of cold-formed steel portal frame structures
, 2014 This paper investigates the effect of semi-rigid joints and finite connection length on the design of cold-formed steel portal frames. The performance of frames sized using a rigid joint and full joint strength assumption is compared with frames having ...

Predesign of steel frames with semi-rigid joints
, 2013 It is well known that real solutions of steel joints in framed structures are far away from the conservative assumption that joints behave like pure hinges and/or full rigid connections. Applying semi-rigid philosophy in the design requires consideration of joint characteristics (M- φ relationship) in the global analysis. The main parameters describing
