On demand of growing population construction of high –rise building is being made compulsory for avoiding land scarcity in future. So these high-rise are difficult to be analyzed manually. So many computerized commercial software are available for analyzing a structure digitally. It uses limit state method in RCC for designing by considering all the standard code books and gives the design. Structural planning and design is an art and science of designing with economy elegance and durable structure. The entire process of structural planning and designing is not only requires imagination and thinking but also sound knowledge of structural engineering besides knowledge of practical aspects such as relevant design codes and by-law backed up by experiences. The purpose of standards is to ensure and enhance the safety, keeping careful balance between economy and safety. The design involves load calculations manually and analyzing the whole structure by STAAD pro and STAAD etc. Complicated and high-rise building need and very time taking and cumbersome calculations using conventional manual methods. STAAD pro provides us a fast, efficient, easy to use accurate platform for analyzing an multi-storey building. Finally we make an attempt to define the economical structure by STAAD.Pro.
