Structural Analysis and Design is the most important part of Building & Bridge Design. The overall building stability depends on it. Cost Effective and safe design is the key responsibility of a structural Engineer. Proper analysis and design lead to a building’s safer Life and Low-cost construction. There are so many parameters to consider in Structural Analysis and Design. Opel Engineers is an Architectural & Structural Engineering Firm with Digital Survey & Soil Investigation & Testing Firm in Bangladesh. We are dealing with Structural Consultancy Services with Digital Survey & Soil Investigation & Testing Since 2015 in Bangladesh. We have designed many Structural designs all over Bangladesh. Bangladesh is situated in an active earthquake-vulnerable zone. So, earthquake-resistant building design is mandatory here. We consider earthquake and wind load while analyzing and design of building structures. There also have special detailing criteria for earthquake-resistant building design in BNBC-2020, Part-6, Chapter-8. We follow these detailing guidelines strictly in all of our structural detailing.
