First in this paper, the guidelines of diagnosis for the seismic performance of traditional timber buildings are introduced which are under development in a committee of the Agency for Cultural Affairs of Japan. Next, the evaluation method of seismic performance proposed in the diagnosis is summarized. Next, as calculation examples, the lateral loaddisplacement relationships of five temple buil...

To evaluate the seismic performance of pre-cast concrete shear wall with vertical reinforcements spliced by two different grout ways, quasi-static tests of two concrete shear walls holed by prefabricated corrugated pipe and one concrete shear wall holed by drawing out the pipe were tested. The test results showed that the wall holed by prefabricated corrugated pipe was basically the same as the...

Abstract To correctly manage the road infrastructure before and after an earthquake, it is necessary to estimate even predict seismic performance of bridge. The quantification bridge's response was present in terms displacement also based on previous research reinforced concrete bridge pier models. did define from a force lateral-displacement diagram corresponding capacity curve, calculated thr...

Abstract A new tool for seismic design is presented, called Yield Displacement Charts (YDC). As with its predecessors, the Point Spectra (YPS) and Frequency (YFS), YDC concept takes advantage of simple features yield displacement ( u y ), to use in a performance-based instead force-based period-dependent approach. self-contained comprehensive approach YPS YFS enabling novel aspect be introduced...

The 1994 Northridge, California, earthquake is the first earthquake for which we have all of the data sets needed to conduct a rigorous regional analysis of seismic slope instability. These data sets include (1) a comprehensive inventory of triggered landslides, (2) about 200 strong-motion records of the mainshock, (3) 1:24,000-scale geologic mapping of the region, (4) extensive data on enginee...

We present the integration of seismic and Ground-Based Interferometric Synthetic Aperture Radar system (GBInSAR) displacement data at Stromboli Volcano. Ground deformation in the area of summit vents is positively correlated with both seismic tremor amplitude and cumulative amplitudes of very long period (VLP) signals associated with Strombolian explosions. Changes in VLP amplitudes precede by ...

In recent years, it is considerably attempted to develop the concept of energy dissipation as an applicable technology to overcome the energy released by earthquakes. The passive control systems such as metallic dampers have been widely considered. The dampers are basically used to mitigate the structural responses and reduce the damages in main structural elements by energy dissipation. ...
