The permanent ground displacement adjacent to the seismic fault is of great interest to many earthquake and structural engineers. The thin layer method is one of the advantageous calculation methods for the dynamic Green’s function in layered soil, which can also be applied to the static problem in terms of a summation of the eigenmodes. Evaluation of ground displacement due to seismic faults requires stress component calculation, which is firstly verified. We use improved calculation method to calculate stress components using secondary elements. Finally, permanent ground displacements are verified to show the feasibility of the proposed calculation methods by comparing with rigorous solutions.

This report describes application and modification of the strong-motion pulse generation area (SPGA) model for the 2011 Tohoku earthquake focusing on strong ground motion simulation in the metropolitan area. Equations for Q values and geometrical spreading are modified to take into consideration far distance from seismic faults, though, resulting in overestimation of the Fourier spectra of ground motions. Finally, the rupture pattern of a SPGA off Ibaraki Prefecture is adjusted from the model by Nozu (2012), leading to better consistency with recorded motions in the metropolitan area.

In the 2011 Tohoku Earthquake, a large number of school gymnasia suffered damage. One of the most typical damage observed in steel roof gymnasia supported by the RC frame is failure at the anchored connections of steel roof bearings on the RC frame. In this paper, the practical evaluation methods that we proposed in our past papers, of the reaction forces at the anchor connections, of the displacements at the roller bearings, and of the design requirements for the friction dampers, are compared with the time history analysis results.

In the Part 2, the observed failure behavior of semi-fixed bearings is graphically described and the strength for horizontal force is evaluated according to the AIJ recommendation.
The damage of base mortar was very similar to that observed after the 2011 off the Pacific coast of Tohoku Earthquake. It is found that the ultimate strength is precisely predicted following to the AIJ recommendation. However, the use of the yield strength is preferable in the strength evaluation for use of the facilities after earthquake. Since the damage of base mortar is not severe for the load level at the yield strength.

An exploratory research on a deployable geodesic sphere for a personal shelter that provides final measure to protect oneself in extreme emergencies is reported. C.Gantes has shown that it is possible to make geodesic hemispheres deployable when elastic bending deformation is allowed to the scissors members. The hemisphere has two stable states, one is in the folded configuration and the other is in the unfolded. The authors have successfully extrapolated the same approach to find the possibility of constructing a full sphere, rather than a hemisphere. The paper describes the detail of the approach, model and some numerical results.

Damage to large membrane roof during heavy snow in February 2014 was investigated. The failure of the membrane roof unintentionally avoided the most dangerous collapse of the main skeleton. The membrane roof has functioned as force-limiter. The author recognized this fact and applied this principle to virtual renovation of another gymnasium roof in the same prefecture, which has been actually collapsed by the same heavy snow.

A number of Japanese cedar, which ought to be used to buildings or other structures, would increase rapidly in a few years in Japan. However the stiffness and strength of the Japanese cedar’s timbers are much less than other timbers in North-America or Europe. In this paper, the construction approach to improve the weakness of the beam’s bending behavior are presented. Four 1/2-scale simply-supported beams, were tested to clarify the bending behavior and the measure to predict them. The construction approach means to use steel-reinforced lamellas made of the Japanese cedar’s timber, in tension zone and compression zone.

A moment resisting joint with lagscrewbolts shows good mechanical performance and aesthetic view due to not exposing the connectors to the outside. However, the beam and column joints rarely showed a brittle shear failure at the panel zone of the column surrounded by the lagscrewbolts. In this research, a joint system reinforced by long wood screws was confirmed to improve the strength properties and prevent from the failure at the early stage. As the results, the maximum shear strength and stiffness increased with increasing the number of the screws embedded with a comfortable space between each lagscrewbolts and edge distance.

The aim of this research is to make a design method for the beam-column joints using coupled columns. This paper is mainly focused on the behavior of the joints after the yield point. Two main factors, shear resistance of dowels and embedding to beam with columns, resist to moment, but the limit state of the joints is dominated by dowels. By considering dowel’s shear resisting properties after yield point, the limit state of the joints can be predicted. The results showed good correspondences with the theory. In addition, the availability of the joint was verified by a series of experiment.

This report describes height-wise distribution of maximum interstory drift angles in super high-rise RC buildings based on earthquake response analysis models for structural design. Yielding loads in the restoring force characteristics are almost consistent for plural buildings when normalized by base shear coefficients. The height-wise distributions of interstory drift angles mainly depends on characteristics of input wave motions. As a result of the response analyses using various pulse waves and harmonic waves, the maximum interstory drift angles in low level floors occur when predominant period of input wave is longer than first natural period of the building.

In the Great East Japan Earthquake, some buildings with the damage of non-structural walls were unable to be used continuously or demolished after the earthquake even if residual structural safety performance of those buildings was enough. In this paper, analysis for SRC building considering the modeling of non-structural wall is performed and the result of repairable evaluation is shown. Specifically, the maximum response deformation of the buildings is computed by the dynamic analysis and predicts the damage state, the validity of the prediction is shown. Furthermore, the relationship between repair time and post-earthquake functional use is discussed.

S-wave velocity of soil layers is needed to calculate earthquake ground responses, but the cost of observing S-wave velocity is high. Therefore, it is often estimated from various soil data such as N-value. However, the variation in the S-wave velocity measured from N-value is very large. The purpose of this study is to examine the effects of this variation on the earthquake response of base isolated houses using a stochastic method. Results show that a soft ground surface leads to a larger the variation of the displacement response.

This research investigated the visual and sound environments perceived at night in 116 open-air cafés. As a result of the investigation, visual elements tended to be perceived stronger than sound elements. Although the sound elements were not perceived frequently, they were evaluated to be comfortable to the same extent with the visual elements. BGM, tableware, lights of the terrace tables, and trees tended to be felt comfortably, and the elements in connection with traffic, such as cars and pedestrian’s voices, tended to be felt uncomfortably. The open-air cafés which continued inside and outside spaces while the pedestrian’s eyes were controlled tended to provide comfortable visual and sound environments.

Aiming to establish a floor impact sound prediction method for deck plate slabs in steel structure buildings, a response analysis of floor vibration by the finite element method with coupling of in-plane and bending displacement was verified. First, damping constants of the actual deck plate slabs were measured. Then, using the measured damping constants, a vibration response analysis which modeled the cross-sectional composition of deck plate slabs and steel H-beams was conducted. The analysis of the vibration response to the standard heavy impact source showed good correspondence with the measurement.

Installing wood stoves into detached houses is becoming popular recently, and is considered to be one solution to realize low-carbon society. Nevertheless, there is few measurements done in Japan to assess indoor thermal environment by wood stoves, making the proper room size heated by one stove unclear. The paper shows the analysis on indoor thermal environment when a room is heated by a wood stove by constructing a detached house with numbers of sensors installed for detailed experiment. After confirming the validity of CFD, methodology to predict proper room size to be heated by a wood stove is introduced.

Information on how much daylighting can reduce the electricity used in illumination is useful for designing green buildings. In this paper, concepts of “daylight area” are reviewed considering several guidelines. Daylighting potential in an area was investigated with a metric known as Daylight Autonomy using a dynamic daylighting simulation software. In the investigated cases, the direction of windows had little influence. In addition, although a simple analysis using daylight factor and diffuse horizontal illuminance is not sufficient to simulate sequential daylighting, it may be useful to predict Daylight Autonomy under the climatic conditions in Japan.

In this study, we conducted a questionnaire survey to determine the installation state of air cleaners and humidifiers in the kindergartens and nurseries in the Tokai region. The results of the survey showed that the installation of these equipment increased rapidly against a backdrop of the epidemic of pandemic influenza in 2009. As younger children and infants stayed at nurseries for long durations, the installation rate of the equipment was higher at nurseries than at kindergartens. However, open windows for ventilation were used as the principal method of preventing infection of influenza at both kindergartens and nurseries.

This paper aims to analyse the changes in pupil numbers and resulting school closures. From 1959 to 1968 the sharp decline in the number of children resulted in the amalgamation and reorganization of schools apace. Between 1969 and 1982 pupil numbers increased and many new schools were established. But after that pupil numbers started to decrease again. As the large scale merging of municipalities took place from 2003 to 2010, many schools shut down. We classified municipalities into 9 categories according to the fluctuation of the number of pupils and schools in them and analysed characteristics of the types.
