This is a retrospective review of nine coronal shear fractures of the distal humerus. Two were isolated fractures and seven were associated with other peri-articular elbow injuries, termed "complex" coronal shear fractures. All cases underwent immediate open reduction and internal fixation (ORIF) and were then followed for an average of 14 months (range: 6.5 to 23 months) with outcomes evaluate...

In the present study, the non-linear response of RC frame using FE modeling under the incremental loading has been carried out in the first phase of analysis to study the response and load-carrying capacity of a four storeyed RC frame using non-linear finite element analysis. In the second phase of study an analysis model for retrofitted RC frame using finite element method using software ATENA...

Fig. 1: Strategy for the evaluation of wall shear stress parameter distribution in the aorta (A) and at the site of complex plaques (B, C). A: 3D-PC-MRA was used to position 8 standardized analysis planes in the ascending aorta (AAo, 1-3), aortic arch (4-5), and descending aorta (DAo, 6-8) for the calculation of segmental WSSmag and OSI. B: For 144 complex plaques, images depicting maximum plaq...

The stiffness of masonry infill walls is commonly neglected in design practice Reinforced Concrete (RC) structures. In fact, the wall may significantly influence seismic performance and dynamic behavior RC buildings. this research, to structural a three-story frame investigated. addition, possible application friction-based support also studied. Full 3D non-linear time history analysis conducte...

BACKGROUND AND PURPOSE Attempts have been made to associate intracranial aneurysmal hemodynamics with aneurysm growth and rupture status. Hemodynamics in aneurysms is traditionally determined with computational fluid dynamics by using generalized inflow boundary conditions in a parent artery. Recently, patient-specific inflow boundary conditions are being implemented more frequently. Our purpos...

This study explores a seismic retrofit method for existing RC columns using cast-in-site partial thick hybrid wing-wall (THW) technique. The THW technique plays two important roles: (1) to enable easy and cost-effective construction (2) considerably increase lateral strength ductility. aim of this is experimentally determine the shear resistance (truss arch mechanism) retrofitted Based on analy...

the present research is concerned with the determination of ductility, over-strength and response modification factors of coupled steel shear wall frames. three structural models with various numbers of stories, bay width and coupling beam height were analyzed using static pushover and incremental nonlinear dynamic analyses. the ductility, over-strength and response modification factors for the...

according to the iranian code of practice for seismic resistant design of buildings, soft storey phenomenon happens in a storey when the lateral stiffness of the storey is lower than 70% of the stiffness of the upper storey, or if it is lower than 80% of the average stiffness of the three upper stories. in the combined structural systems containing moment frames and shear walls, it is possible ...

A new type of strengthening technique for existing reinforced concrete (RC) shear walls was proposed using steel wire mesh (SWM) and polymer mortar. The experimental campaign consists testing one conventional RC wall specimen four specimens strengthened different configurations ratios wrapping methods under cyclic lateral loading. results showed that the application meshes mortar not only delay...

The application of ECC materials in major stress and energy dissipation regions prefabricated reinforced concrete (RC) shear walls to form ECC/RC combined can improve the seismic capacity structures. damage mechanism a 1/2-scale two-story spatial structure specimen wall under low cyclic loading is numerically simulated. By comparing numerical simulation results with experimental results, correc...
