This paper comprehensively analyzes a typical school building, energy consumption patterns, and constant usage. Besides that, the effect of building conditions on school energy consumption is discussed. The findings of this study indicate that typical school buildings are usually in the south direction where site plan adjacent to the buildings around could lead to some challenges in energy efficiency. The energy consumption pattern reveals two categories, Category 1 has high fluctuation for monthly energy consumption and Category 2 has relatively flat consumption. Thus, two categories may have different site conditions.

Long-term key issues in the earthquake-resistant design of building structures are combats with resonance and damping. Nonlinear resonance problems are reformulated as critical excitation problems for elastic–plastic structures under a simple impulse sequence. The double impulse (DI) with two impulses of opposite directions is introduced as a simple representative model of near-fault pulse-type ground motions. The interval of such impulses is treated as a parameter to derive the critical input. Another critical excitation problem is considered for elastic–plastic building structures under the multi impulse (MI) representing long-period, long-duration ground motions. These critical excitation problems are solved by using an energy balance approach between the kinetic energy and the strain-dissipated energy. It is pointed out that this paradigm shift enables a smart capture of nonlinear resonance in structural dynamics, which has been thought to need intrinsic repetition of numerical computation. It is also found that this paradigm shift fills a gap between two historical hypotheses (constant energy criterion, constant displacement criterion) in the earthquake-resistant design of building structures.</p>","PeriodicalId":42793,"journal":{"name":"Japan Architectural Review","volume":"8 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2025-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/2475-8876.70037","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144524600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The specimen was tested under two configurations: first, with the Spine rigidly connected to the MRF; second, with the Spine connected to the MRF through force-limiting connections (FLCs). Each specimen configuration underwent earthquake simulations using ground motions with two scale factors. The tests demonstrated the expected benefits of Spines as well as the disadvantage of inducing large floor accelerations in the structure and large shear forces in the Spines. The tests also demonstrated how the FLCs can mitigate these disadvantages. This data paper reports an overview of the tests, data archive structure, and potential use of the data.

The initial rulings can be conical or cylindrical surfaces. By means of inputting the ruling lengths, the 3D configuration of the origami model can be obtained. To decrease the number of unknowns, the ruling lengths are mapped by control points of Non-Uniform Rational B-Spline (NURBS) techniques. The numerical example demonstrates the feasibility of finding curved origami with both dome-like and saddle-shaped surfaces and tubular models.
