FRP (Fiber-Reinforced Polymer) and SMA (Shape Memory Alloys) were the most popular materials used to strengthen RC beams (e.g., [10]–[27]).
This illustrated the broad field of materials and methods available for enhancing the durability and performance of RC beams in various structural scenarios.
The rebar was encased in concrete, the host region, to facilitate optimal interaction between materials.
Similar to the use of advanced materials such as Glass Fiber-Reinforced Polymer (GFRP) composites in enhancing the compressive behavior of concrete columns as discussed in [33].

Study on Two-Dimensional Packing Problem ZHOU Dexiang1 , WANG Xianrong2 and CHEN Shengda3 College of Information Science and Technology Henan University of Technology Zhengzhou, China e-mail: zhoude_xiang@sina.com, 64526682@qq.com Computer Science Department, XiaMen University, Xiamen, China Keywords- Two-dimensional packing, HR algorithm, IHR algorithm Abstract—IHR was proposed in this paper based on HR algorithm which defines reference rectangle and binding layer.
Introduction Packing problem is a very important topic in the field of theoretical computer science and combinatorial optimization[1].
As the development of computer science, management science, modern production technology, more and more combinatorial optimization problems which applied in the mathematics, computer science and management science and many other disciplines is being paying more and more attention.

Analysis and Design of Offshore Pile Foundation Sudip Basack1, a 1Associate Professor of Applied Mechanics Bengal Engineering and Science University, Howrah 711103, India abasackdrs@hotmail.com Keywords: Amplitude, Cyclic Load, Degradation, Frequency, Pile, Soil Abstract.
Initially, solutions were developed under static loading idealizing the pile as elastic beam and the soil as a non-linear material.
In the model, the soil was idealized as a nonlinear material while the pile as elastic-perfectly plastic.
