This paper presents a new model for predicting the compressive strength of steel-confined concrete on circular concrete filled steel tube (CCFST) stub columns under axial loading condition based on Artificial Neural Networks (ANNs) by using a large wide of experimental investigations. The input parameters were selected based on past studies such as outer diameter of column, compressive strength...

In December 1961, Letournel [10] published his original series on acetabular fracture classification and operative management. Before that time, acetabular fractures were classified as those associated with posterior hip dislocation and those associated with central hip dislocation. Many were treated without surgery, resulting in poor articular congruity of the hip. Citing an increasing inciden...

Damage to adobe constructions might occur due a long wall and lack of effective restraint in the middle wall, causing it collapse under an earthquake. Aiming at these problems, technology for improving seismic performance modified adobe-brick-masonry composite with wooden-construction center column is proposed. It uses mud, wooden column, steel-wire mesh, nylon ropes reinforce wall. On this bas...

We address the problem of optimizing operation of a process where there are extra degrees of freedom, and where the optimum is not at some constraint. In practice, there are always unknown disturbances and model uncertainties which make this task complicated. The key idea of this paper is to turn the non-linear optimization control problem into a setpoint control problem so that we achieve “sel...

Using the formula of shear bearing force of oblique cross section in eccentrically loaded column, we analyze the stress acting on short-leg shear wall and conventional eccentrically loaded column. We propose the formula for calculating the shear bearing force of oblique cross section of short-leg shear wall that considers the action of vertical reinforcing steel bars, flange and axial compressi...
