IRJET Journal

Steel structures are generally more flexible than other types of structure and lower in weight. Earthquake loads are random in nature. It is difficult to predict them exactly. The action applied to a structure by an earthquake is a ground movement with horizontal and vertical components. The horizontal movement is the most specific feature of earthquake action because of its strength and because structures are generally better designed to resist gravity than horizontal forces. These forces produce large stresses, strains, deformation and displacement particularly in tall structures. To keep displacement within limit generally bracing is provided in steel structure. . Bracings are generally used to increase lateral-stiffness, lateral- strength as well as lateral stability of the frame. Variations in the column stiffness can influence the mode of failure and lateral stiffness of the bracing. In this study steel frame is modeled and analyzed three Parts viz., (i) Model without Steel bracing (bare frame), (ii) Model completely with fully braced steel frame („Cross‟ bracing), (iii) Model completely with fully braced steel frame („Single diagonal‟ bracing).

The present work depicts mathematical behavior of a vehicle mounted platform/frame integrated with chassis structure in terms of plane stresses and plane strains for non-uniform loads. The load type considered in present work is concentrated load for which the mathematical model is formulated. A different type of combination of longitudinal and cross members in platform/frame design is formulated. The dimensions of platform members are determined using IS standards. After analysis of all possible combinations of longitudinal and cross members present design is anticipated. Section properties of longitudinal and cross members of the platform are determined & deduction of bending stress and shear force based on the load pattern are the fundamental steps in design and analysis of platform structure. The peculiarity of this analysis is the calculation of combined section modulus of three members. These are evaluated by excel programs developed indigenously.

The size and shape of opening in dam causes the stress concentration, it also causes the stress variation in the rest of the dam cross section. The gravity method of the analysis does not consider the size of opening and the elastic property of dam material. Thus the objective of study is comprises of the Finite Element Method which considers the size of opening, elastic property of material, and stress distribution because of geometric discontinuity in cross section of dam. Stress concentration inside the dam increases with the opening in dam which results in the failure of dam. Hence it is necessary to analyses large opening inside the dam. By making the percentage area of opening constant and varying size and shape of opening the analysis is carried out. For this purpose a section of Koyna Dam is considered. Dam is defined as a plane strain element in FEM, based on geometry and loading condition. Thus this available information specified our path of approach to carry out 2D plane strain analysis. The results obtained are then compared mutually to get most efficient way of providing large opening in the gravity dam.

This study presents the procedure for seismic performance estimation of high-rise buildings based on a concept of the capacity spectrum method. In 3D analytical model of thirty storied buildings have been generated for symmetric buildings Models and analyzed using structural analysis tool ETABS. The analytical model of the building includes all important components that influence the mass, strength, stiffness and deformability of the structure. To study the effect of concrete core wall & shear wall at different positions during earthquake, seismic analysis using both linear static, linear dynamic and non-linear static procedure has been performed. The deflections at each storey level has been compared by performing Equivalent static, response spectrum method as well as pushover method has also been performed to determine capacity, demand and performance level of the considered building models. From the below studies it has been observed that non-linear pushover analysis provide good estimate of global as well as local inelastic deformation demands and also reveals design weakness that may remain hidden in an elastic analysis and also the performance level of the structure. Storey drifts are found within the limit as specified by code (IS: 1893-2002) in Equivalent static, linear dynamic & non-linear static analysis.

In this study, Non-linear response of concrete with differential value of YoungÃ¢â‚¬â„¢s Modulus is determined by the stress strain expression. The modulus of elasticity is varied throughout to evaluate the non-linear response of concrete structure at a constant load. The modeling of structure is done in STAAD PRO Vi8 software. In this study, single storey-single bay frame is modeled which is subjected to dead load and uniform loads, has been considered for the non-linear response of concrete structures. A structural element such as Column is used for evaluation of the non-linear response of concrete material. From this, deflection of the column element is carried out by using STAAD PRO software with different initial tangent modulus of elasticity at a constant loading.

The shell structure consists of a thin reinforced concrete shell without the use of internal columns to create an internal opening., parabolic or spherical cross section. On the other hand, warehouses and playgrounds are conventional concrete frame structures, on the other hand, they can be difficult to design as the exact shape required for the stability of the structure depends on the material used, the dimensions of the enclosure, external or internal loads and other chamfers.. .. Thus, by changing the shell parameter, the performance of the shell will also change. The main goal of this work is to parametrically analyze different designs of cylindrical shells of different lengths in order to analyze two different lengths of taken cylindrical shells, and then change two parameters, first the radius and then the thickness, based on the radii. and the difference in thickness for the same width, length and material of the frame, we will evaluate the behavior of the frame for different models.

IRJET - Study on Horizontal Curved Bridge – State of Art Literature Review

IRJET Journal

Reinforced concrete column with varying cross-sectional dimensions are commonly used in many engineering structures since use of such elements in a structural system may reduce the weight of the system, since neither axial load nor stiffness is constant along the column height the stability analysis of a stepped column is usually more complicated than that of a uniform column. The lateral forces can produce critical stresses in the structure, induce undesirable vibrations or cause excessive lateral sway of the structure. The present study deals with the comparison of Concentric Non-Prismatic columns and Stepped columns under the effect of static, wind and dynamic loads with the help of ETABS Software.

Abstract This paper introduces the comparison between lateral load resisting systems in multi storey building. Multi storey building composed of very special class of structure and therefore require special treatment. Hence to overcome the effects of seismic forces, Flat slab system in which slab rests on drop or capital which is connected to column is induced with different load resisting systems. The combined systems which is used to withstand seismic forces in this study are 1. Flat slab without lateral load resisting system, 2. Flat slab with shear wall, 3. Flat slab with infill wall, 4. Flat slab with bracings, 5. Flat slab with shear wall and bracings. ETABS software version is used to accomplish dynamic analysis and also building is investigated for nonlinear static analysis in order to identify seismic demands. From the obtained results conclusions are drawn. Keywords: Capital, Bracings, Dynamic, and Treatment etc…

Moment resisting frames are commonly used as the dominant mode of lateral resisting system in seismic regions for a long time. The poor performance of Ordinary Moment Resisting Frame (OMRF) in past earthquakes suggested special design and detailing to warrant a ductile behavior in seismic zones of high earthquake (zone III, IV & V). Thus when a large earthquake occurs, Special Moment Resisting Frame (SMRF) which is specially detailed with a response reduction factor, R = 5 is expected to have superior ductility. The response reduction factor of 5 in SMRF reduces the design base shear and in such a case these building rely greatly on their ductile performance. To ensure ductile performance, this type of frames shall be detailed in a special manner recommended by IS 1392. Special proportioning and detailing requirement results in frame capable of resisting strong earthquake shaking without significant damage. These moment resisting frame are called as “Special Moment Resisting frames”. In this study, the buildings are designed both way as SMRF and OMRF, and their performance is compared. For this the buildings are modeled and pushover analysis is performed in SAP2000.

WhatsApp +27737758557 *Cheap Clinic* Abortion pills for sale 50% Off Online What are (Cytotec) abortion pills? The abortion pill should not be confused with the morning after pill as it is intended for use within the first 12 weeks of pregnancy whereas the morning after pill should only be used within 3 to 5 days after intercourse. The abortion pill, Misoprostol, is an approved pregnancy termination method in South Africa How does an Abortion Pill work? Both abortion pills, mifepristone and misoprostol, are usually used in order to terminate a pregnancy. Mifepristone causes the embryo to detach from the uterus thereby cutting off essential nutrients and oxygen carried by the blood. Misoprostol is then taken two days later and triggers the evacuation of the embryo remnants through the vagina. This often appears as a heavy period. Is the Abortion Pill safe? The abortion pill is usually safer than a medical abortion or surgical abortion but should only be considered up to 24 weeks (Or 7months) of pregnancy. Medical Abortion pills can be delivered to you just Call Us to make a desired Delivery Counter or Door call on +27737758557 If you’re looking for quality Birth Control Treatment, then Cheap Top Women’s Clinic is the Women’s Health Clinic for you.
