Broadly defined, a joint is a structural relation between two individual bodies so that mechanical forces are transmitted from one body to the other. But many other aspects, such as aesthetics and compatibility with the system or product functions, also contribute to designing a joint. This project is a study of various joints in modular systems and focuses on problems related to panel joinery systems. Various principles in joinery are analysed and some different ideas are suggested for the joining of FRP panels.

About modular joints:
• Joints in modular systems are designed for a particular set of modules considering their sizes ,shapes, materials and variations.
• Modules and joints are developed together, and joints add to the character of a modular system.
• Joints determine the configuration of modules.
• They allow fast assembly and knock-down of the prefabricated modules.
• Modules and joint elements are reusable after knock-down without any work on the material.
