Abstract Technological advancements have greatly aided in improving quality of life through variety of new products and services. Pre Engineered Building (PEB) is among such technological advancement in the structural engineering. PEB concept provides optimum design, good aesthetic view, fast rate of construction and reduction in erection time. PEB satisfies a broad range of custom design needs and applications. This methodology is adaptable not only because of its high quality pre-designing and prefabrication, but also of its flexibility. In the current study, the comparison has been made on the structural performance of multiple bay system with different wind zones [Locations: Vijayawada and Hyderabad]. Analysis and design have been carried out using STAAD.Pro software. The structural performance of pre-engineered building has been assessed through the shear force (SF) and bending moment (BM) magnitudes. Based on the output of SF and BM of pre-engineered components through Staad. Pro analysis, the geometrical properties of pre-engineered sections have been decided. Results concludes structure weight located in Vijayawada is 11.04% higher than that of the structure in Hyderabad.

Relative Gains

This work was undertaken to compare the use of BS 8110 and Eurocode 2 in the design of structures and focused on outlining the relative gains and/or shortcomings of Eurocode 2 and BS 8110 under certain criteria which are loading, analysis, ease of use and technological advancement. To accomplish this, the analysis and design of the main structural elements in reinforced concrete building was undertaken using the two codes. A modest medium rise building was loaded using the two code and analyzed. Analysis was done using CSI start tedds to obtain the shear force and bending moment envelopes. For the beam, it was found that Eurocode 2 gave higher internal supports moments. For the case of maximum span moments and shear force values, the Euroode 2 values lagged behind. Column load and moments values were generally lower for Euroode 2. In summary, the comparative benefits of using Euroode 2 are that it is logical and organized, less restrictive and more extensive than the BS 8110. The new Eurocodes are claimed to be the most technically advanced code in the world and therefore should be adopted by Nigerian engineers. http://dx.doi.org/10.4314/njt.v36i3.14

A bridge is a combination of substructure and superstructure that is built over a river, road, or railway to allow people and vehicles to cross from one side to the other. This paper describes about the analysis and design of box girder balanced cantilever bridge using MIDAS CIVIL by IRC loadings, characterized by central span of 130m with two symmetrical sides of 85m.Bridge deck is supported by two piers of 40m height from ground level. The bridge structure has been modelled using MIDAS CIVIL and analysis has been performed to get various output such as bending moment, shear force and time dependent properties such as creep and shrinkage at various points of the bridge. The PSC (prestressed) design of superstructure is performed as per IRC standards to get the output parameters such as principle stresses at construction stage, principle stress for prestressing tendon. While by using balanced cantilever bridge less form work has been required for this type of bridge.

Architectural engineering, also known as building engineering, is the application of engineering principles and technology to building design and construction. Definitions of an architectural engineer may refer to an engineer in the structural, mechanical, electrical, construction or other engineering fields of building design and construction; a licensed engineering professional in parts of the United States; in informal contexts, and formally in some places, a professional synonymous with or similar to an architect. Structural engineering involves the analysis and design of physical objects (buildings, bridges, equipment supports, towers and walls). Those concentrating on buildings are responsible for the structural performance of a large part of the built environment and are, sometimes, informally referred to as “building engineers”.

Abstract Pre-stressed concrete bridge analysis is completely dependent on the standards and design criteria. Herein, the current study compares like a pre-stressed concrete bridge under the effect of two different loading standards and specifications. The two different loading standards considered herein are IRC 6: 2000 and AASHTO-LRFD standards. Further, the pre-stressed box girder bridge is modelled and analysis in MIDAS CIVIL. On carrying out analysis, the primary structural analysis parameters which are important for the design of structure, are studied. These parameters are shear force, bending moment and torsion in the bridge elements along its length. It became observed that AASHTO standards are uneconomical than IRC standards, due to consideration of heavy weight vehicle load moving on the bridge span. Thus, it might be said that pre-stressed box girder bridge analysis and design should be carried out effectively and optimistically using IRC standards and specifications.

Analysis and design of beam is still an important part in Structural Engineering practice. As a major component in structure, it demands due attention and accuracy. At the same time engineers need to achieve economy in time and cost in the design of beams. To assist designers moment coefficients are developed for continuous beams in this work. Existing ACI moment coefficients are applicable only under certain conditions and have some limitations. This study is an attempt to develop moment coefficients for beams which will be applicable beyond ACI limitations. Comparison of developed coefficients with corresponding ACI coefficients has been done and a satisfactory agreement is found. However, ACI coefficients are found to be conservative. Additionally design tables are developed for selection of RC beam section and reinforcement when design bending moment and shear are available. SAP2000 has been used for analysis of beams during the study. Models are used to generate exact moment coefficients for beams of different span ratios and spans under uniform loading. The moment coefficients and design tables generated in this work will be useful for practicing engineers for quick design. KEY WORDS: Moment Coefficient; Shear; Continuous Beam; Uniform Loading.

AbstractTo evaluate the relationship between muscle fiber characteristics and the quality of frozen/thawed pork meat, four different muscles, M. longissimus thoracis et lumborum (LTL), M. psoas major (PM), M. semimembranosus (SM), and M. semitendinosus (ST), were analyzed from twenty carcasses. Meat color values (lightness, redness, yellowness, chroma, and hue) changed due to freezing/thawing in LTL, which showed larger IIAX, IIX, and IIXB fibers than found in SM (P < 0.05). SM and ST showed a significant decrease in purge loss and an increase in shear force caused by freezing/thawing (P < 0.05). Compared with LTL, SM contains more type IIXB muscle fibers and ST had larger muscle fibers I and IIA (P < 0.05). PM was the most stable of all muscles, since only its yellowness and chroma were affected by freezing/thawing (P < 0.05). These results suggest that pork muscle fiber characteristics of individual cuts must be considered to avoid quality deterioration during frozen storage.

This study aimed to investigate the moment carrying behavior of typical Tibetan timber beam-column joints under monotonic vertical static load and also evaluate the influence of length ratio of Gongmu to beam (LRGB) and dowels layout on the structural performance of the joint. Six full-scale specimens were fabricated with same construction but different Gongmu length and dowels position. The moment carrying performance of beam-column joints in terms of failure mode, moment resistance, and rotational stiffness of joints were obtained via monotonic loading tests. Test results indicated that all joints are characterized by compressive failure perpendicular to grain of Ludou. Additionally, it was found that greater LRGB leads to greater initial rotational stiffness and maximum moment of the joint by an increase of restraint length for beam end; however, offsetting dowels toward column resulted smaller stiffness and ultimate bending moment of joints, particularly, offsetting Beam-Gongmu dowels toward column changed the moment-rotation curve pattern of the beam-column joint, accompanied by a hardening stiffness at last phase. Furthermore, a simplified trilinear model was proposed to represent the moment-rotation relationship of the typical Tibetan timber beam-column joint.

Quadratic Relationship

Mixing of cattle prior to slaughter which results in aggressive activity (Mohan Raj et al 1992) leads to glycogen depletion pre-slaughter and subsequently meat with a higher ultimate pH (pHu). Purchas et al (1990) reported a quadratic relationship between pHu and tenderness with highest shear force values recorded between pHu 5.8 to 6.2. The aim of this study was to determine the effect of fasting and mixing of steers prior to slaughter on the meat eating quality of longissimus dorsi (LD) muscle.
