Water tank is a container used for the storing of liquids and they are classified based on shape and location. The overhead tank is an important and it is very common public utility structure. The study predicts the analysis and design of the rectangular and circular overhead water tank using ETABS software. The water tank is modeled and analyzed by using dynamic analysis to resist lateral loads and design is made using working stress method manually. Dead load, live load, wind load and seismic loads are applied based on IS codes. The behavior of structure for the parameters like Story drift, displacement, stiffness, deflection, storey shear, base shear, area of steel and hoop tension for circular and rectangular water tank are studied and then comparison of the results is made between circular and rectangular overhead water tank. By this study we say that the circular water tank is suitable for larger capacity and rectangular is suitable for smaller capacity and it is economical for larger capacity.

Plan Configuration

With the application of modern technologies in Civil Engineering, construction of high rise buildings with irregular plan configuration is increasing very quickly. Multi-story buildings are prone to lateral loads from wind or earthquake, which necessitates the need of seismic studies. Buildings can be designed to reduce these lateral loads by many methods; which is why the action of structural diaphragms have to be studied. Several studies have shown the effect of plan configuration on base shear, displacement and story drift, torsional buckling. The lateral stiffness of the building frame affects the maximum displacement of the structure due to earthquake. Study is done on various plan configuration buildings and the action of structural diaphragm on its performance during earthquake is studied.

Based on a ductile frames 15 level building, a non-linear analysis with increased monotonically lateral loads (Push-Over) was made in order to determine its collapse and its principal responses were compared against the elastic and inelastic time-history seismic responses determined with the SCT-EW-85 record. The seismic-resistance design and faced to gravitational loads was made according to the Complementary Technical Norms of Concrete Structures Design (NTC-Concrete) and the NTC-Seismic of the Mexico City Code (RDF-04), satisfying the limit service states (relative lateral displacement between story height maximum relations, story drifts ≤ 0.012) and failure (seismic behavior factor, Q= 3). The compressible (soft) seismic zone IIIb and the office use type (group B) were considered. The non-linear responses were determined with nominal and over-resistance effects. The comparison were made with base shear force–roof lateral displacement relations, global distribution of plastic hinges, failure mechanics tendency, lateral displacements and story drift and its distribution along the height of the building, local and global ductility demands, etc. For the non-linear static analysis with increased monotonically lateral loads, it was important to select the type of lateral forces distribution.

When the multi-storied buildings are constructed a suitable care should be taken while designing, as they are subjected to lateral forces. The behaviour of multi-story building depends upon either in plan or in vertical direction i.e, elevation, is considered as one of the main causes of failure during earthquakes. Thus irregular structures, especially the structures which are located in seismic zones are required a special attention during analysis and design of structure. In this study Plan irregular (C-shaped building) is considered to carry out study. Bracing system is installed to provide strength against lateral loading and the behaviour of the structure in terms of base shear, story drift, stiffness and the lateral displacements are observed. Three different types of bracings X, V and Diagonal are installed in the structure. Total 4 models are analysed for 7 story height level, 4 Models are computed to determine the performance of the structure. One MRF and three models with different bracing system. And the best suitable bracing system for this study. The method used for this study is response spectrum method, to perform dynamic analysis of the structure.

The consequences of lateral loads like earthquake loads, wind loads and blast forces are achieving utmost concern nowadays. Imparting sufficient strength and stability in counter to the lateral loads is one of the major challenges faced by every designer. Therefore Proper understanding of the Seismic performance of different types of shear walls is necessary for structural engineers so as to safeguard the structure against lateral loads. The present paper describes the comparison of the seismic performance of high rise buildings and optimizing the thickness of RCC shear wall, Steel Plate Shear Wall (SPSW) and composite shear wall for (G+20) stories. The design and analysis of the  building with RCC shear wall, steel plate shear wall and composite shear wall is carried out using software ETABS. Effect of varying thickness of shear panels and comparison of the results of story drift and story shear is presented.

This study presents the shake-table tests of a 1/5-scaled RC frame retrofitted with RC infill walls. The intensity of input ground motions increased gradually to comprehensively evaluate the structural seismic behavior. We performed a comparison of the results from the RC frame with masonry walls and that with RC walls. The results showed that the presence of RC infills effectively improved the lateral structural stiffness and loading capacity of the frames and reduced their damage and story drift. RC walls acted as the first seismic line of defense, and their failure was dominated by bending failure and concentrated on the low stories. The displacement ductility of the structure decreased with increasing stiffness of the introducing infills.

Abstract: Structural analysis is the science of determining the effects of different loads on structures. Structural stability and stiffness are a main concern in any high-rise structures. Shear walls are structural members that are mainly responsible for resisting lateral loads predominant on structures. They are mainly responsible to increase the stiffness, reduce story drift and displacement. In order to have a comprehensive understanding about the contribution of shear wall, following research is carried out. This research involves comparing two G+16 structures; one without a shear wall and one with it. The structure has 4 bays of 3m each along X direction and Z direction. In this, we will see how shear wall resists lateral sway and reduces story drift and increases stiffness. As the height increases, the shear wall absorbs more lateral load than the frame. The software to be used for analysis is STAADPro. Keywords: STAADPro, Stiffness, storey displacement, storey drift.
