    (AIKTC, 2020-05) Shaikh, Wasim; Syed, Umamah (14CE60); Shaikh, Ahmed Raza (12CE49); Dalvi, Maaz (15CE15); Shaikh, Nawaz (13CE56)
    Recent trend of growth in population and scarcity of land has evolved an era of modern urbanization which indeed has led to the vertical growth of buildings and gave us the new trend setting structures named as High Rise Structures or Multi-Storeyed Structures. These structures are need of time due to scarceness of land, greater demand for business and residential space, economical emergence, technical advancements, innovations in structural systems and desire for aesthetics in urban area. Lateral load effects on high rise buildings are quite significant and increase rapidly with increase in height. In high rise structures, the behavior of the structure is greatly influenced by the type of lateral system provided and the selection of appropriate. The selection is dependent on many aspects such as structural behavior of the system economic feasibility and availability of materials. Few of the lateral structural systems are Shear wall system, Braced frame system, Framed tube system, Tube in tube system, Bundled tube system. The lateral structural systems give the structure the stiffness, which would considerably decrease the lateral displacements. In the present work Shear-wall system, framed tube system and tube-in-tube systems are considered for 21, 41 and 61 story structures. The analysis has been carried out using software Etabs. Earthquake Load is given in form of Spectrum load referring to IS 1893-2002 and Wind load is given as per norms of IS 875-Part III 1987. The Storey displacements, base-shear, member forces such as shear force and Bending moment in beams and columns, forces in shear-wall are also studied and compared. It is seen that the Shear wall system is very much effective in resisting lateral loads for the structures up to 20 stories and for structures beyond 20 stories the Framed tube system is very much effective than Shear wall system in resisting lateral loads.

    Effect of environment on the strength and shrinkage of concrete
    (AIKTC, 2021-05) Shaikh, Wasim; Qadri, Sayyed Altamash (17CE43); Kazi, Qais Bashir (17CE44); Khamkar, Naveed Naushad (17CE19); Shaikh, Mohammed Tauseef (17CE54)
    The most important constituent of any structure is concrete. It is widely used in every construction project because of its physical and chemical properties. Concrete has a long-life span but everything deteriorate with time and the main reason of deterioration of concrete structure around the world is the weathering effect or we can say the effect of environment. Our environment consists of lot of different constituents. These constituents place a major role in the deterioration and destruction of the structure. The main reason for the destruction of the structure is the decrement in the strength of the concrete because of various different environment agents such as pH, temperature and the shrinkage due to the various conditions. In this paper we are going to study and analyze the effect of different environmental condition on the strength and shrinkage of concrete. This will help us to understand more about the behavior of concrete even though the exact behavior of concrete cannot be determined accurately. By this data the estimation of strength will be predicted more accurately.

    Evaluating performance and costing of green building
    (AIKTC, 2016-05) Mahajan, Girish; Kaji, Sadik; Shaikh, Wasim; Nachan, Aarish
    Development is gradually converting the bio diverse habitat in to a concrete jungle which consists of an impervious cover to landscape resulting into a lack of woodland habitat and conservation of the most precious element on the earth “WATER”. The vast canvas of built environment necessitates a greener color into it picture. Sustainable development is a development that “meets the needs of the present without compromising the ability of future generations to meet their own needs” Sustainable construction tries to incorporate the general sustainable development concepts into conventional construction practices. One of the ways to achieve sustainable construction is the Green Building Design, which is the core area of attention for greener built environment. Green Building Designs have environmental considerations as a basic scrutinizing criteria which attempts to integrate and achieve concepts of energy efficiency, water conservation and recharge, solid waste management, exploration of renewable energy resources, use of eco friendly materials and to minimize the negative impact on the nature, plant and animal species, non renewable material conservation and preserve resources and processes that prevail in nature. Several Green Building Rating Systems have been developed to objectively evaluate energy and environmental performance that spans the broad spectrum of sustainability.

    Explosion analysis on framed structure by using finite element method
    (AIKTC, 2018-05) Shaikh, Wasim; Gani, Mohd Riyaz (15DCE68); Farooqui, Mohd Hasnat (15DCE67); Jinna, Zaidh Ali (15DCE62); Mulla, Afreen A (13CE1)
    Blast is an explosion which is a rapid release of potential energy characterized by eruption enormous energy to the atmosphere. A part of energy is converted to thermal energy radia- tion ( ash) and a part is coupled as air blast and shock waves which expand radially The Finite Element Method (FEM) is a numerical technique to nd approximate solutions of partial di erential equations. It was originated from the need of solving complex elas- ticity and structural analysis problems in Civil, Mechanical and Aerospace engineering. In a structural simulation, FEM helps in producing sti ness and strength visualizations. The solution to the numerical model equations are, in turn, an approximation of the real solu- tion to the PDEs. The nite element method (FEM) is used to compute such approximations The terrorist activities and threats have become a growing problem all over the world and protection of the citizens against terrorist acts involves prediction, prevention and mitigation of such events. Explosive is widely used for demolition purposes in military applications, construction or development works, demolitions, etc. It is, also, a very common terrorist weapon as it is available, easy to produce, compact and with a great power to cause structural damage and injuries. In this report we have explored the available literature on blast loads based on standard structural analysis software with limited linear and non-linear capabilities. Apart from this we have performed mesh sensitivity analysis by taking into account various mesh sizes and corresponding de ection is computed. The analytical results are obtained based on the load vs de ection curve for linear and non linear properties of concrete. It is shown that with the present knowledge and common software, it is possible to perform the analysis of structures exposed to blast loads and to evaluate their response

    optimization of shear wall for high rise buildings
    (AIKTC, 2018-05) Shaikh, Wasim; SHAIKH, TALHA (14CES46); KHAN, AYAZ (14CES18); KHAN, FAISAL (14CES28)
    In the present construction industry, the buildings that are constructed are gaining significance in general, those with best possible outcomes with reference to optimal sizing and reinforcing of the structural elements mainly beam and column members in multi-storey RC structures in particular. The concept of “Best possible outcome” is called optimization. Optimization plays an important role in structural design, the very purpose of which is to find the best solutions from which a designer or a decision maker can derive a maximum benefit from the available resources. Shear wall provides large strength and stiffness to the building in the direction of their orientation which considerably reduces lateral sway of the building and there by reduces damage to the structure. If a high rise R.C. Structure is designed without shear wall the beam and column sizes are large and so many problems arises at the joints and due to this it is difficult to place and vibrate the concrete at such places and displacement is more which in turn induces heavy forces on the structure therefore shear wall become essential from the point of view of economy. By providing shear wall the structure become safe and durable and also more stable the function of shear wall is to increase rigidity for wind and seismic load resistance

    As we know Concrete is strong in compression and weak in tension because of structural cracking at a relatively low level of stress, it means concrete doesn’t behave same in tension and compression but Steel reinforcement bars behave similarly in tension and compression. The stress–strain response of concrete in compression is nearly linear at the beginning of loading up to approximately 0.7 fc . Beyond that stress, the response becomes highly nonlinear up to failure. The ultimate strength of concrete in tension is relatively low.
