In this study we tried to consider effect of vertical component of  near zone earthquake (10 to 15 km far from fault) such as Kobe 1995, Northridge 1994, Loma prieta 1989 and Chichi 1999 on a concrete cable bridge by a 320m span in the middle which was built on different type of soils. The SAP software (version14) was selected because I should have done linear and non-linear time history anal...

field observations of the incurred damages to the buildings and bridges due to earthquakes in near field show there are various failure modes which are in relation to the forces caused by vertical component. while vertical component of earthquake for ordinary buildings in most seismic regulations and standards is not considered. therefore, in the current study the effects of vertical and horizo...

In this study, an artificial neural network was used to predict the minimum force required to single point incremental forming (SPIF) of thin sheets of Aluminium AA3003-O and calamine brass Cu67Zn33 alloy. Accordingly, the parameters for processing, i.e., step depth, the feed rate of the tool, spindle speed, wall angle, thickness of metal sheets and type of material were selected as input and t...

The purpose of this study is to identify human walking vertical force by using FFT power spectrum density from the experimental acceleration data of the human body. An experiment on human walking is carried out on a stationary floor especially paying attention to higher components of dynamic vertical walking force. Based on measured acceleration data of the human lumbar part, not only in-phase ...

Patients with Multiple Sclerosis (MS) suffer from inabilities such as weakness and muscle fatigue due to the demyelination. The inabilities may result in some disorders in walking. The present study is a clinical trial research conducted on 84 participants in two groups of experimental and control who were randomly selected. The results showed that people with MS apply more force on the ground ...

The aim objective of this study is to investigate the effects of near-field earthquakes on the response of mid-rise buildings with tubular structure.  For this purpose, a 20-story building with a square plan of six by six bays, all with 6 m span, and story height of 3.70 m is considered.  Axial force of columns, shear lag, and inter-story drift values are used as the main response parameters. N...

OBJECTIVE To find out if it is possible to control maxillary anterior teeth in sagittal and vertical plane during retraction by altering the vertical levels of force application in the posterior region, i.e. identifying the type of movement of the maxillary anterior teeth which occurs when force would be applied from four different levels i.e. High, Medium, and Low pull Implants and from a conv...
