Purpose of class
Course content
The Structural Systems Laboratory (Ishikawa Lab) conducts research on cutting‑edge structural systems that form the foundation of architecture, cities, and the environment. In earthquake‑prone Japan, the laboratory focuses on developing next‑generation resilient reinforced concrete (RC) systems, including high‑strength steel fiber reinforced concrete (SFRC) structures, high‑strength concrete‑filled steel tube (CFT) structures, and timber–RC hybrid structural systems (patent application filed in 2023) to enable the realization of super high‑rise buildings. In addition, the laboratory is advancing the research and development of timber–RC hybrid structural systems that contribute to a resource‑circulating society. Through engagement in these leading‑edge research activities, the laboratory aims to cultivate the next generation of professionals who will shape the future of the field.
Goals and objectives
  1. Students will be able to identify the structural engineering challenges that Japan and the rest of the world must address today, understand their current conditions, and propose new research topics based on this understanding.
  2. Students will be able to understand the properties of advanced structural materials—such as steel fibers developed in Belgium and LVL/CLT products widely used in New Zealand—and propose appropriate methods for their application in architectural and structural engineering.
  3. Students will be able to formulate research plans and carry out both experimental and analytical studies on advanced research topics in structural engineering.
  4. Students will be able to submit research papers to academic conferences in Japan and abroad and present their work effectively.
  5. Students will enhance their fundamental professional competencies by taking responsibility for portions of multiple collaborative research projects conducted in partnership with industry, including companies such as Bekaert (Belgium), Haseko Corporation, Shimizu Corporation, Sato Kogyo, Nihon Sekkei, and Mori Building.
