We would like to introduce a case study of the primary and secondary seismic diagnosis program for RC/SRC structures, "DOC-RC/SRC." At Kanebako Structural Design Office, they are not only satisfying the required seismic performance but also pursuing the potential for seismic retrofitting that adds further value to the buildings through reinforcement design. In recent years, the number of seismic diagnosis and retrofitting projects has increased, reaching 10% of their overall business, and they were considering purchasing a seismic retrofitting and diagnosis program. The decisive factor for adopting DOC-RC/SRC was its high operability. Since it inherits the input from the structural calculation program "BUS-5," which is a consistent structural system, it is easy to operate and allows for CAD-like input. The output results are presented in full color, neatly organized with chapters and page breaks, making them easy to read and verify. Additionally, the ability to directly input indicators of ductility and strength based on the situation provided significant flexibility, which was a major factor in the adoption decision.

We would like to introduce a case study of the structural calculation software "WALL-1" for wall-type reinforced concrete buildings. At the office of Shuji Tada Structural Design, they handle numerous structural designs for wall-type residences of 100m² and 200m² scale, as well as compact apartment buildings with a total floor area of around 200 to 1000m². In residential and small-scale apartment buildings, most reinforced concrete structures are wall-type. As they began to handle nearly 10 wall-type projects annually, and due to the stricter confirmation application process following the earthquake falsification incident, they considered introducing wall-type integrated structural calculation software. "I was recommended 'WALL-1' by an acquaintance as being easy to use, and after trying it out, I found it very user-friendly because it allows for smooth insertion of openings and enables the creation of approximate models in a short time to obtain results. It has a good reputation among cooperating offices, which led us to decide to implement it. We started using it around 2009, and now we use WALL-1 for almost all our projects. Since WALL-1 has a proven track record, it is favorable for confirmation applications." For more details, please contact us or refer to the catalog.

We would like to introduce a case study of the vibration analysis tool "SNAP." Yamashita Design, Inc. is one of Japan's leading comprehensive design firms, responsible for the Kasumigaseki Building, the first super high-rise building in Japan. Recently, proposals emphasizing structural planning have become essential for securing contracts for the design of government and private facilities, with seismic isolation design becoming standard in hospital architecture and vibration control structures in office buildings. The need for response analysis using three-dimensional models has been increasing to analyze complex structures. Due to the impact of legal revisions and the need to adapt to advancements in analysis technology, maintaining and managing in-house programs has become challenging, leading to the decision to adopt commercial programs, with "SNAP" being one of the options. Since there are currently few case studies of its adoption, when creating models in SNAP, we verify input data and calculation results while working, and we have reached out to support with questions whenever doubts arise. The support staff are well-versed in the program's details, providing prompt and courteous responses. For more details, please contact us or refer to the catalog.

Kataoka Design Co., Ltd. is an architectural design office established in 1982. Their design projects primarily focus on single-family homes, but they also handle multi-family residences, stores, factories, offices, and hot spring inns, covering a wide area across the Kanto region. "When I became independent, I strongly felt that the future of design was in the CAD era, so I introduced computers and CAD software. After consulting with industry professionals and visiting various places to decide which CAD to use, I chose DRA-CAD, which had been adopted by major design firms and general contractors, had a large user base, and was highly regarded for its ease of use. Since it was my first experience with computers, I took foundational courses to learn, but DRA-CAD's operation felt very close to hand-drawing, which was a great help. I started using CAD at the age of 45 after purchasing a computer, and even after turning 60, I am still actively drawing plans, which makes me feel that my way of thinking and my choice of DRA-CAD were indeed the right decisions."

The staff of the Architectural Design Department at Daiho Construction Co., Ltd. handles a wide range of architectural design, primarily focusing on apartments, offices, and factories. The design drawings created by our 20 engineers are all designed using DRA-CAD. "We introduced it around 1991-1992, when CAD was not yet widespread. At that time, I believe there were few CAD software options available, but we decided to adopt DRA-CAD from Structural Systems, a leading manufacturer of architectural design drafting software, because we had confidence in it, and we have continued to use it to this day. There have been suggestions to switch to other companies' software several times, but each time we concluded that we should maintain productivity with the user-friendly DRA-CAD, and we still use it today. Especially since DRA-CAD is a domestically produced CAD, I believe it matches the drawing sensibilities of Japanese designers." "The drawings produced in-house range from general drawings to detailed drawings, all created using DRA-CAD. While it is primarily used for drafting tasks, I think it is a CAD with very high expressive power. It is also very useful for creating planning drawings and is greatly utilized in planning and presentations." For more details, please contact us or refer to our catalog.
