Three-dimensional spatial structures have advantageous features to conventional planar frame structures. Spatial structural systems are usually highly efficient with lightweight and high rigidity. Some of them are mechanically flexible or environmentally adaptable. The efficiency of the spatial structures is usually due to their morphological nature.

Current research topics of the lab. are as follows:
• Development of new lightweight structural systems,
• Static and dynamic behavior of spatial structures,
• Safety of the large enclosures,
• Tension structures (Membrane or tensegrity structures,)
• Adaptable/Deployable Structures,
• Seismic performance and dynamic control of lightweight structures,
• Morphological aspects of structures and mechanical behavior of plates and shells.
