B.; Selokar, G. R.; varane, A. L.; Narkhede, R. S. Abstract: There are many details for reinforced concrete frame joints. Few of these details could satisfy the strength requirements, cracking and ductility. But the joint are still the weakest part in structural system. Observations made after earthquake, accidental loading shows that breakdown at the joint is the most frequent cause of failure of element connected. Distribution of stresses at an opening corner indicates that high tensile stresses exist at the inner corner normal to diagonal, coupled with tensile stresses along the diagonal. This paper explains the objectives to strengthen the joint to avoid the tensile stresses which causes the diagonal cracks at the joint. Five types test models are considered to analysis having different attachment to the corner for strengthening purpose. The models are subjected to heaviest load. Analyzed by using Stad-pro. The solid steel plates are found as an outstanding solution but attachment is very difficult. Chamfering is also helpful to this condition but cracks are developed in this case. The two angular plates are used to avoid diagonal cracks Fri, 16 Jun 2017 00:00:00 GMT http://localhost:8080/xmlui/handle/123456789/2624 2017-06-16T00:00:00Z http://localhost:8080/xmlui/handle/123456789/2600 Title: Performance and Properties of Concrete with Waste Concrete as a Coarse Aggregate Authors: Narkhede1, Rajendra S.; . Selokar1, Dr. G. R; Dr. G. R Abstract: Construction and demolition waste generation has exceedingly increased around the world. About 40% of construction and demolition waste is generated annually. Out of various types of construction and demolition waste, concrete constitutes about 80% of the total waste. Therefore, it is necessary to recycle concrete waste to recycled aggregate and recycled aggregate concrete. The workability and strength properties of the aggregate obtained from the demolished waste concrete are reported in this paper. An attempt has been made to compare the physical and mechanical properties of the conventional concrete aggregates and that of aggregates obtained from the demolished waste concrete. In the present experimental work, it has been decided to conduct studies on three mixes of concrete namely M15, M20 and M25 which are generally and widely used in practice. The recycled coarse aggregates are mixed in different percentage 0 %, 25%, 50%, 75%, and 100% along with the natural aggregates Thu, 03 Aug 2017 00:00:00 GMT http://localhost:8080/xmlui/handle/123456789/2600 2017-08-03T00:00:00Z
