Complex and Lightweight Tensegrity Structure Under Dynamic and Impact Loads; State of the Art

Most of the structures we build nowadays are of RCC, pre-stress, steel, or composite materials. To rest these structures on soil with low bearing capacity, the self-weight of the structure has always been a challenge. As the self-weight of structure is directly impacted by its material density, engineers have traditionally struggled to design structures that are low in weight. A problem in engineering necessitates a solution, and a tensegrity structure, with its lightweight and high strength to self-weight ratio, provides the optimum solution. But their complicated geometry and shape make analysis extremely difficult, and it has always been a challenge for the researchers to analyze these structures with dynamic and impact loads. This research work aims to study the tensegrity structures and their response under dynamic and impact loads. For this, more than 50 research papers have been studied, and from the previous work, it has been found that there is very little or no work on complex tensegrities under the consideration of dynamic and impact loads and shape of optimization of complex tensegrities. It is also observed that, due to recent advances in civil engineering, there has been a surge in attention in active structures in the recent years, tensegrity structures being one, fulfill the demand. Further the work also states that when a natural or man-made disaster strikes, the need to quickly accommodate people arises. Such disasters also highlight the need for lightweight, transportable, and adaptable buildings that can be adapted to the environment and modified to support a variety of activities, and tensegrity structures can be one the solutions for this.
