Experimental observations on three reinforced concrete shear walls with small span-to-depth ratio (SDR) under combined high vertical axial load and horizontal cyclic loads are presented. The influence of (ALR) the failure mode, hysteretic behaviour, displacement ductility, strength stiffness squat is investigated. In addition, a novel built-in strain gauges measuring system employed for conditi...

Upgraded design standards coupled with the damage caused by natural disasters have led to development of smart materials potential modernize current construction practices. This investigation proposes a nonlinear finite element (FE) model for evaluating performance beam–column joints (RC-BCJ) reinforced shape memory alloys (SMA) and steel rebars. The was validated based on accredited experiment...

The conventional lingual arch is a nonfunctional fixed space maintainer used in the mandibular arch to maintain arch length by the prevention of mesial movement of the permanent first molars. This study highlights a functional lingual arch with a hinge-type lockable dentulous component that incorporates molar tubes, with various advantages over the conventional lingual arch. How to cite this ...

In the current practices of structural design, the concept of moment redistribution in conjunction with linear analysis is well known and widely accepted. There are numerous studies and various references that deal with the issue and different codes propose various provisions for the amount of permissible redistribution. Despite numerous advantages, there are some limitations in the available w...

Shape memory alloys (SMAs) are unique smart materials that have many advantages, such as ability to resist large strains without leaving residual strains and ability to recover original form. However, the high costs of SMAs have limited their usage. This paper evaluates the behavior of concrete structures equipped with SMAs in an optimal manner as they are being used along the plastic hinge of ...
