		Construction Safety Research Group

The Construction Safety Research Group studies the requirements for the safe conduct of construction work and to improve methods for the working environment at construction sites. The main subjects of the research are safety in temporary work, safety in earthwork, prevention of accidents involving falls and slipping, and safety assessment of newly developed methods of construction work.

1. Preventing the collapse of temporary structures

The following subjects are studied: dynamic properties of earthquake and wind loads acting on temporary structures during work; structural stability under a variety of loads; strength of structural members and connectors; safe procedures for the assembling work or dismantling work of temporary structures.

Experiment name

	Wind tunnel tests for prevention of the collapse of temporary structures due to strong winds.
	Bucking test of wedge-type scaffolds.

2. Prevention of accidents during earthwork

The following geotechnical studies are conducted to ensure safety during earthwork: evaluation of the stress-strain characteristics of soils, clarification of failure mechanisms of earth collapse using centrifuge models for testing, development of prediction methods for earth collapse, and safety evaluation of temporary systems of earth support.

Experiment name

	Geotechnical centrifuge testing apparatus.
	Trench failure simulation using centrifuge models for testing.

3. Preventing falls

To analyze falls caused by slips, foot movements of falls are generated on the floor and studied. In walking experiments, a suspended fall-arresting device is used to protect subjects from actual falls. Dummies are used to test the sliding properties of various roofing materials on an experimental adjustable-pitch roof. The safety requirements for scaffoldings and lifelines are also studied.

Experiment name

Surface testing of roofing materials for sliding and falling properties.

4. Safety evaluation for new construction methods

Methods of safety assessment and preventive countermeasures are studied for the prevention of accidents associated with deep ground construction, construction of huge bridges, and construction under all weather conditions.

Experiment name

	Simulating the overturning of mobile crane due to outriggers sunken into ground.
	Tower crane model using table test.
