Construction automation and robotics are being introduced as an efficient alternative to overcome troubles caused by lack of skilled labors. To accomplish effective automated construction system, design for automation(DFA) should be performed in parallel with the development of core technologies such as control and sensing of robots. In Korea, the development of robotic crane-based construction automation(RCA) system is progressing, and the research group has recently developed newly designed steel joint to improve the efficiency of the system. However, performance of the new system should be examined prior to its application on construction sites. Therefore, This study analyzed performance of the new steel frame focused on its constructibility by carrying out mock-up test. As a result, the steel frame satisfied the standards of allowable stress and deflection. It also enables to reduce the time for installation.

FormWorks-Plus is a generalized public domain user-friendly preprocessor developed to facilitate the process of creating finite element models for structural analysis programs. The lack of a graphical user interface in most academic analysis programs forces users to input the structural model information into the standard text files, which is a time-consuming and error-prone process. FormWorks-Plus enables engineers to conveniently set up the finite element model in a graphical environment, eliminating the problems associated with conventional input text files and improving the user's perception of the application. In this paper, a brief overview of the FormWorks-Plus structure is presented, followed by a detailed explanation of the main features of the program. In addition, demonstration is made of the application of FormWorks-Plus in combination with VecTor programs, advanced nonlinear analysis tools for reinforced concrete structures. Finally, aspects relating to the modelling and analysis of three case studies are discussed: a reinforced concrete beam-column joint, a steel-concrete composite shear wall, and a SFRC shear panel. The unique mixed-type frame-membrane modelling procedure implemented in FormWorks-Plus can address the limitations associated with most frame type analyses.
