本研究は中国農村部の住宅建設におけるマルチリブ複合壁構造（MRCWS）の適用可能性を評価。振動台試験による耐震性能の確認、プロセスベースLCAとEFAによる炭素排出分析、LCCとDCMによるコスト評価を実施。従来のレンガ造りと比較し、MRCWSは炭素排出を約6%、コストを約10%削減することが示された。農業廃棄物（麦わら）を活用し、耐震性も確保する新規プレハブ構造は、農村住宅の持続可能性向上に貢献する。
English
This paper evaluates a multi-ribbed composite wall structure (MRCWS) for rural housing in China, using shake-table tests for seismic performance, life cycle assessment for carbon emissions, and cost analysis. Compared to traditional brick masonry, MRCWS reduces embodied carbon by 6% and costs by 10%, while using agricultural waste (wheat straw) and meeting seismic standards. It offers a low-carbon, cost-effective solution for rural construction.

📄 Abstract（原文）
Sustainable development is crucial worldwide. Under the Paris Agreement, countries commit to Nationally Determined Contributions (NDCs) assessed every five years. China, a major contributor to global warming, has made significant efforts to reduce carbon emissions and achieve carbon neutrality, a key strategy for sustainable development. However, there is a lack of adequate attention to embodied emission reduction in rural residential construction, despite a surge in building to improve living standards. This paper evaluated the feasibility of applying a multi-ribbed composite wall structure (MRCWS) in rural China through a village service project. A full-scale shaking table test was conducted to study its seismic performance. Carbon emissions were analyzed using process-based life cycle assessment (P-LCA) and the emission-factor approach (EFA), while costs were estimated using life cycle costing (LCC) and the direct cost method (DCM). These analyses focused on sub-projects and specific structural members to validate the superiority of this prefabricated structure over common brick masonry. MRCWS blocks were prefabricated by mixing wheat straw with aerocrete, utilizing agricultural by-products from local farmlands, thus reducing both construction-related carbon emissions and agricultural waste treatment costs. Results show that this novel precast masonry structure exhibits strong seismic resistance, complying with fortification limitations. Its application can reduce embodied carbon emissions and costs by approximately 6% and 10%, respectively, during materialization phases compared to common brick masonry. This new prefabricated building product has significant potential for reducing carbon emissions and costs in rural housing construction while meeting seismic requirements. The recycling of agricultural waste highlights its adaptability, especially in rural areas.
