Torsion or twisting is a common concept in mechanical engineering systems. This section looks at the basic theory associated with torsion and examines some typical examples by calculating the main parameters. Further examples include determination of the torque and power requirements of torsional systems.
Pushover is a static-nonlinear analysis method where a structure is subjected to gravity loading and a monotonic displacement-controlled lateral load pattern which continuously increases through elastic and inelastic behavior until an ultimate condition is reached. Lateral load may represent the range of base shear induced by earthquake loading, and its configuration may be proportional to the distribution of mass along building height, mode shapes, or another practical means.
The static pushover analysis is becoming a popular tool for seismic performance evaluation of existing and new structures. The expectation is that the pushover analysis will provide adequate information on seismic demands imposed by the design ground motion on the structural system and its components. The purpose of the paper is to summarize the basic concepts on which the pushover analysis can be based, assess the accuracy of pushover predictions, identify conditions under which the pushover will provide adequate information and, perhaps more importantly, identify cases in which the pushover predictions will be inadequate or even misleading.
Mathcad P-elements linear versus nonlinear stress 2014-t6Julio Banks
This work couples the classical ESED (Equivalent Strain Energy Density) Method; aka, Glinka. The most expedient method of solving a structural problem using FEA (Finite Element Analysis). There would be occasions when stress concentrations would be calculated due to interior corners, holes, sudden change of geometry (aka stress raisers). Although some software would allow regions in the vicinity of such stress risers to be defined by nonlinear material models such as "Elastic Perfectly-plastic", "Bilinear (Elastic and linear plastic), or the fundamental Ramberg-Osgood metal strain-stress models. Once the Linear-elastic FEA solution is obtained one can readily determine that Pseduo nonlinear strain, the corresponding stress and the implicit stress-intensification factor, Kt. It should be noted that once the analyst-designer is ready for final analysis, it would be most prudent to create a FEA model in which the regions of high concentration of stress to be modeled with local nonlinear models of the metal using St. Vennants' Principle of load-and-resistance distance from area of interest. The P-method is an excellent FEA element that can "find the actual nonlinear stress" by the simple iterative increase of the order of the polynomial representing the stress fields within every P-element. It should be noted that this research was facilitated by the use of the P-element FEA software called StressCheck which is 100% P-element solution which I am quite pleased to have had the opportunity of utilizing for this research.

BEHAVIOR OF SLENDER COLUMN SUBJECTED TO ECCENTRIC LOADINGijiert bestjournal
This paper focuses on Behavior of slender column su bjected to eccentric loading. Six slender,reinforced concrete columns with slenderness ratio equals to 15;the compressive strength of the concrete were ranged from 60 to 100 MPa. Slender co lumn were subjected to eccentric axial load with load-eccentricity:depth ratio of 0.15. Three columns were reinforced with six bars having a nominal strength of 415 MPa and other three were re inforced with same number of bars having strength equals to 500 MPa with longitudinal steel ratio equals to 4%. The test results were compared with the values predicted using IS 456-200 0. These test,enabled the provision for slender columns in the code to be checked against e xperimental values,have indicated that IS 456-2000 are very safe and uneconomical design docu ment for HPC slender column.

Design of short sstt confined circular hsc columnseSAT Journals
Abstract Steel-straps tensioning technique (SSTT) has been proven to be an effective mean to confined High-strength concrete (HSC). The pre-tensioned force offers by this confining method can significantly restraint the small lateral dilation of HSC. However, most of the design guidelines only concerned with FRP-confined columns subjected to concentric compression. The direct application of these design guidelines on the SSTT-confined HSC column is being questioned due to different material and confining method adopted. Hence, a numerical study was carried out in the view of developing a simple design equation for HSC column confined with SSTT. The parameters such as SSTT-confinement ratio, load eccentricities and slenderness ratio were tested. Based on the numerical results, design equations based on regression analysis were proposed to determine the ultimate load and bending moment of SSTT-confined HSC columns. Index Terms:Confinement, Steel Straps, Eccentric loads, and Theoretical Model.
The Effect of Structure -Soil Interaction on Eccentrically Loaded FrameIJERD Editor
The interaction among structures, their foundations and the soil medium below the foundations alter
the actual behaviour of the structure considerably than what is obtained from the consideration of the structure
alone. Thus, a reasonably accurate model for the soil–foundation–structure interaction system with
computational validity, efficiency and accuracy is needed in improved design of important structures. The
framed structures are normally analyzed with their bases considered to be either completely rigid or hinged.
However, the foundation resting on deformable soils also undergoes deformation depending on the relative
rigidities of the foundation, superstructure and soil. Interactive analysis is, therefore, necessary for the accurate
assessment of the response of the superstructure.

Shear behavior of reinforced concrete slender beams using high strength concreteeSAT Journals
Abstract
An experimental investigation is carried out on Nine Slender HSC beams with constant size 125mm x 130mm and effective length
900mm by varying (i) The longitudinal reinforcement ratio and (ii) the web reinforcement ratio were casted and tested to understand
the shear behavior of the beams with minimum web reinforcement as per IS CODE and ACI CODE and maximum web reinforcement.
The load-deflection behavior and the failure pattern of the beams, ultimate shear strength are studied with varying longitudinal
reinforcement and varying shear reinforcement. The experimental results obtained are compared with the theoretical values as per
code. Based on these observations, it can be concluded that, there are many parameters influencing the shear behavior of RC beams
such as shear span to depth ratio (a/d ratio>2), concrete grade, depth of the beam, the percentage of the longitudinal reinforcement
and shear reinforcement. It can be concluded that, the shear failure is brittle, sudden and very explosive. As the spacing of shear
reinforcement reduced (75mm) the load carrying capacity increased and as the spacing of shear reinforcement increased (225,
300mm) the load carrying capacity decreased. Shear failure is characterized by small deflection, lack of ductility and catastrophic
failure.
Keywords: High strength concrete, shear span to depth ratio, failure pattern, ultimate shear capacity, codal provisions.
This research introduces a new simple, efficient, and practical procedure to design
the reinforced concrete (RC) circular slabs which have large diameters. The principal
idea of this paper concerns to use the isotropic perpendicular RC straight joists to
resist the external load. The yield-line theory was adapted to analysis the circular
waffle slabs. The steps of design were according to the ACI Code provisions. Fixed
and simply supported circular slabs were presented. Closed form equations have been
driven by author for the purposes of analysis and design this type of slabs by the
present procedure. Uniformly distributed load was considered, that represent almost
practical cases. Useful illustration example is presented in this study according to the
available materials in Iraq to facilitate the job of designers. The good performance of
RC circular slab which design by the present procedure proved clearly the efficiency
of this technique.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
