A new type of self-centering rocking wall that allows gap opening both at the bottom and the top, has been proposed to be used as window piers. This aims to reduce the da [...]

The modern seismic design of building is concerned with two distinct performance levels: protecting human lives in the case of large earthquakes, and provide structural s [...]

Twenty-some years ago, it was considered that safety was a major and only concern in designing building structures in an engineering society. However, the 1994 Northridge [...]

Damage analysis was conducted on the static loading test data of the full-scale five-story reinforced concrete building utilizing wing walls for damage reduction. In expe [...]

In major earthquake, many reinforced concrete buildings were damaged. Some of the buildings had severe economical losses due to structual or nonstructual damage until aft [...]

A revised edition of Standards for Structural Calculation of RC Structures was published by the Architectural Institute of Japan in 2010. It relaxed requirements on bound [...]

Static loading test was conducted on four 40%-scale specimens in order to evaluate the shear transfer mechanisms of structural walls with eccentric openings. Specimen con [...]

In the current design cord of AIJ(Architectural Institute of Japan), the minimum strength reduction factor of a structural wall due to the openings is limited to 0.6 by r [...]

This research aims to propose economical structural system which reduces seismic damage and needs no or little repair combing precast prestressed concrete (PCaPC) structu [...]

Structural walls are supported by foundation beams and piles that transfer earthquake-induced forces from the structural walls to the soil. In the current design procedur [...]
