Since the Great Hanshin-Awaji Earthquake, the need for restoration, disaster prevention, and seismic performance evaluation and reinforcement of traditional wooden buildings has been increasing in order to preserve them for future generations. However, the models of traditional wooden structures are complex. To verify the deformation characteristics and stress states of members during assumed earthquakes, analytical tools capable of handling complex modeling are required. The Architectural Research Association has introduced "SNAP" and is conducting seismic performance evaluations and reinforcement projects for many traditional wooden buildings. The report on the elastic-plastic analysis of arbitrary-shaped three-dimensional frames using SNAP can be viewed by downloading the catalog.

We would like to introduce a case study of the primary and secondary seismic diagnosis program for RC/SRC buildings, "DOC-RC/SRC." At Kanebako Structural Design Office, we are not only satisfying the required seismic performance but also pursuing the potential for seismic retrofitting that adds even more value to the buildings through reinforcement design. In recent years, the number of seismic diagnosis and retrofitting projects has increased, reaching 10% of our overall business, and we were considering purchasing a seismic retrofitting and diagnosis program. The deciding factor for adopting DOC-RC/SRC was its high operability. Since it inherits the input from the structural system's integrated structural calculation program "BUS-5," it is user-friendly and allows for CAD-like input. The output results are presented in full color, neatly organized into chapters and pages, making them easy to read and verify. Additionally, the ability to directly input indicators of ductility and strength according to the situation added significant flexibility, which was a major factor in our decision to adopt it.

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, we handle numerous structural designs for wall-type houses of 100m² and 200m² scale, as well as compact multi-family residences with a total floor area of around 200 to 1000m². In residential and small multi-family buildings, most of the reinforced concrete structures are wall-type. As we began to handle nearly ten wall-type projects annually, and due to the stricter regulations on confirmation applications following the seismic fraud incident, we considered the introduction of wall-type integrated structural calculation software. "I was recommended 'WALL-1' by an acquaintance as being user-friendly, and after trying it out, I found it very easy to use because I could smoothly input openings and create a rough model in a short time to get results. It has a good reputation among cooperating offices, so we decided to implement it. We started using it around 2009, and now we use WALL-1 for almost all our projects. WALL-1 has a proven track record, so 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 Corporation is one of Japan's leading comprehensive design firms, known for handling 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, it became challenging to maintain their in-house programs, leading to the decision to adopt commercial software, with "SNAP" being one of the options. Since there are currently few case studies using SNAP, when creating models, we verify input data and calculation results while working, and we have reached out to support with questions whenever uncertainties arise. The support staff are well-versed in the program's details, providing prompt and thorough 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 throughout 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, I decided to adopt DRA-CAD, which was already being used 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. Purchasing a computer and starting CAD at the age of 45, and still actively drawing plans even after turning 60, makes me feel that my way of thinking and the 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 condominiums, as well as offices and factories. The design drawings created by the 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 very 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 now. Particularly, since DRA-CAD is a domestically produced CAD, I think 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 mainly used for drafting tasks, I believe 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 the catalog.
