Article Abstract
An efficient linear elastic iterative method is proposed for the stability ultimate capacity of equal-leg angle towers, using an elastic modulus adjustment strategy in this paper. The angle steel stability generalized yield function (GYF) of AS/NZS4600 is selected, on which a precise homogeneous generalized yield function (HGYF) is developed through dimensionless analysis and regression. Based on the HGYF, the element bearing ratio is proposed as a dynamic threshold for distinguishing high-stress and low-stress elements in equal-leg angle elements. Then, an adaptive elastic modulus adjustment strategy is proposed for the linear elastic iterative analysis of the stability ultimate capacity of equal-leg angle towers. Compared to analytical solutions and traditional numerical methods, it can be observed that the linear elastic iterative method for the stability ultimate capacity of equal-leg angle towers is accurate and efficient.

A variational model that describes the interactive buckling of a thin-walled equal-leg angle strut under pure axial compression is presented. A formulation combining the Rayleigh-Ritz method and continuous displacement functions is used to derive a system of differential and integral equilibrium equations for the structural component. Solving the equations using numerical continuation reveals progressive cellular buckling (or snaking) arising from the nonlinear interaction between the weak-axis flexural buckling mode and the strong-axis flexural-torsional buckling mode for the first time-the resulting behaviour being highly unstable.

Study Aim: Preoperative planning is regarded as an important requirement for successful implantation of a hip replacement. One of the crucial aspects of planning is the restoration of the normal anatomy of the hip as this increases the chances for good clinical function and reduces wear debris. Various systems for restoration of the hip are available including stem systems with different stem sizes and offsets and so-called modular stem systems which have the additional possibility of adjusting the neck length and angle.

Objective: To investigate the pathogenesis, diagnosis, and treatment of the gluteal muscle contracture associated with an unequal leg length caused by the pelvis obliquity (GMC-PO).
Methods: The retrospective analysis was made on the clinical features and the follow-up results in 132 patients who had been admitted from January 1990 to December 2004 for GMC-PO. Among them, 73 were male and 59 were female with a range in age from 5 to 26 years (average, 11 yr).
