2   1          Introduction   In recent times, researchers are trying to findsuitable replacement for conventional materials of building construction forsustainable development. Need of construction activities increase day by daywith increase of population. Provide a structure with acceptable cost andprevent environmental degradation by construction process are the responsibilitiesof people who related in construction industry. Concrete and steel are mostcommonly used materials in construction and it consumes high percentage cost oftotal budget.

In reinforced concrete structures steel acts as very importantrole to recover the problem in concrete. Concrete is very strong in compressionand have high durability. But the problem is it is weak in tension. So steel isused with concrete to recover the problem because steel is strong in tension.That’s why steel has higher demand in the world and it causes to increase thecost of steel. Researchers found that timber like bamboo, palmayrahare good replacement material for steel and many researches also carried out inthis subject. But they found many problems in using timber as reinforcematerial and gave a solution to overcome some of these problems.

Use timber asa part of reinforcement with steel (hybrid reinforcement) in concrete is bestsolution to get rid of the disadvantages in using timber. In this case bamboois selected as reinforce material with steel because it reaches its full growthin few months and have higher tensile strength compare with other timber materials. It is already reported that bamboo can use asreinforcement material in concrete for light weight elements. It is because ofbrittle nature of bamboo, low stiffness and low compressive bearing capacity. Waterabsorption of bamboo is one of the major problems and it causes to swelling andshrinkage of bamboo in concrete.

Study on effect of water absorption of bambooin concrete and treatment methods were already investigated by researchers.Some coating is used to prevent the water absorption of bamboo in concrete andvarnish is one of the best water repellent we can use. Bonding strength isanother important factor in concrete and bond between bamboo and concrete isrelatively low compare with that of steel and to improve the bond betweenbamboo and concrete bamboo should be treated.      2         Problem statement Even there are many limitations found in use of bamboo or any timber as reinforcementin concrete, swelling and shrinkage is one of the major problem and strainvariation of these materials also very different from that of concrete. Manyresearches were carried out in using timber materials as reinforcement inconcrete and done experimental tests to analyze the mechanical properties oftimber. But still there is no any standard code or method to use timber inreinforcing. So design engineers avoid using timber material in concreteelements in their design.

That’s why this method is not become popular anddemand for steel is increasing day by day. So it needs to find some theoretical models and analyze its performancewhen bamboo use as reinforcement with steel in a different percentage. 3         Significance of the research Most of the researches focused on using timber materials in concrete tofully replaced steel. Because of the disadvantages which already discussed inintroduction part, no one preferred to use this method and don’t want to takerisk. In this situation this study should give a solution to overcome theseproblems and fortify the belief in usage of timber in concrete.

   4         Scope of the study By analyze the slab concrete element which consist both steel and bambooreinforcement give an awareness of using natural materials with eco friendlyand sustainability to the society and people who involved in constructionindustry .     5         Aims and objectives of the research The aim of this research is find a more appropriate proportion of steeland bamboo using as reinforcement in concrete by analyze the concrete slabelement. Objective of this research consider as follows:·        Analyzethe performance of this hybrid reinforcement slab by physical model.·        Obtain thestrain variation of this element. ·        Finiteelement modeling of this element using Midas software to compare theresults and to predict some theoretical models.

 6         Proposed methodology First of all, througha literature review find the objectives of this research and followingmethodology was adopted.                          7         Work plan  8         Budget  9         References  .   Use APA 6th Reference style for thereferences/bibliography and in-text citations.       Submission Rename your file as “CE4902A01_Index no”and submit the pdf format files via Moodle and the submission portal willappear on 10th January 2018 until 12th January 16:00 hrs.
