Objective: This study investigated the short-term effects of two stability exercises, including Abdominal Hollowing and Abdominal bracing on stabilization parameters of Biodex Stability System in male subjects with non-specific recurrent low back pain. Materials & Methods: This Randomized Clinical Trial and case–control study was performed on 30 male subjects with non-specific recurrent low ...
Structural fuses, easily replaceable sacrificial elements to dissipate seismic energy while preventing damage to the gravity loadresisting structural system, are proposed as part of a multicolumn accelerated bridge construction (ABC) pier concept. Different types of structural fuses are investigated to compare the effect of each on ABC bridge bents. The piers of a three span-continuous bridge p...
Concrete filled tubes (CFTs) composite columns have many economical and esthetic advantages, but the behavior of their connections is complicated. Through this study, it is aimed to investigate the performance and behavior of different connection configurations between concrete filled steel tube columns and bracing diagonals through an experimental program. The study included 12 connection suba...
In this paper, a real-time monitoring system—including vibration acceleration sensors, temperature and static dynamic strain sensors—is used to monitor the safety status of steel assembly bracing in practical project. It uses 5G wireless networking technology transmit data cloud server for early warning abnormal changes development trends. Real-time obtained construction site are as inputs fini...
Study Design. A retrospective review of 34 patients with juvenile idiopathic scoliosis (JIS) treated with a nighttime bending brace. Objective. To determine the effectiveness of part-time bracing in JIS. Summary of Background Data. Although previous bracing studies have focused on adolescent idiopathic scoliosis, no authors have dealt specifically with part-time bracing for JIS. Methods. Twenty...
This paper presents a general analysis on the shear stiffness of spine bracing systems of selective storage racks in the down-aisle direction. Unlike the architectural steel structure, the bearing capacity of bracing connection in the spine bracing systems of steel rack structure is weaker than that of bracing members. Firstly, destructive tests of spine bracing connection in single entry racks...
The utilization of orthotic devices for lumbar degenerative disease has been justified from both a prognostic and therapeutic perspective. As a prognostic tool, bracing is applied prior to surgery to determine if immobilization of the spine leads to symptomatic relief and thus justify the performance of a fusion. Since bracing does not eliminate motion, the validity of this assumption is questi...
“Cold-formed steel (CFS) stud walls” are innovative alternative for construction of walls in buildings. The main frames of CFS walls consist of a group of vertical members called “studs” which are hold by fasteners within two horizontal members called “tracks” at the upper and lower ends. One of the conventional ways for designing and analyzing of CFS stud walls under blast loading is to employ...
