Evaluation of Construction Quality Management Based on Fuzzy Matter-Element Analysis

Maomao Li — 2026-05-12

This study develops a construction quality management evaluation framework for prefabricated residential projects by integrating the analytic hierarchy process (AHP) with fuzzy matter-element analysis. Taking Phase II of the Qinxing Jiayuan Anju Community project as a case study, a multi-level evaluation index system was established based on the characteristics of prefabricated construction. The framework comprises six criterion dimensions, personnel management, material management, machinery and equipment management, technical management, on-site management, and information management, and 27 specific indicators, combining both qualitative and quantitative measures. Qualitative indicators were assessed through expert scoring by 30 project-related personnel, while quantitative indicators were derived from project records, including attendance rate, material acceptance rate, ex-factory qualification rate of prefabricated components, transportation and storage loss rate, and RFID/QR code coverage. Indicator weights were determined using AHP, and the overall evaluation grade was obtained through fuzzy matter-element modelling based on membership functions. The results show that the overall construction quality management level of the case project is good (M4). Among the criterion dimensions, material management reaches the outstanding (M5) level, while personnel management, machinery and equipment management, technical management, on-site management, and information management are all evaluated as good. These findings indicate that the proposed framework is practically applicable for structured assessment of construction quality management in prefabricated residential projects.

The Value and Creation Strategies of “Non- Digitizable” Sensory Experiences in Physical Exhibition Spaces

Yifan Wang — 2026-05-12

While digital technologies bring immersive experiences to exhibition spaces, they also give rise to a crisis of “digital flattening”, the compression of rich sensory experiences into visually dominant data streams. Grounded in phenomenology and embodied cognition theory, this paper proposes the concept of “non-digitizable sensory” experiences and deconstructs it into four dimensions: material tactility, bodily scale, atmospheric field, and interactive traces. It systematically discusses their irreplaceable value at the cognitive, emotional, social, and cultural levels. Subsequently, four major strategies are constructed: the method of material tactile narration, the method of bodily movement choreography, the method of holistic atmospheric control, and the method of participatory trace design. Through case studies, the dialectical relationship of “physicality as the foundation, digital technology as the tool” is verified. This research aims to provide both a theoretical pathway and practical tools for exhibition design to return to human-centered experience.

A Review of the Impacts of Shading Technologies on Building Performance

Weizheng Chen — 2026-05-12

Against the backdrop of advancing the “dual carbon” goals and the growing urgency of building energy conservation needs, shading technology, as a key means to regulate the indoor light-thermal environment of buildings and reduce building energy consumption, is of great significance for improving the comprehensive performance of buildings. This paper systematically reviews the impacts of shading technologies on building performance, defining the research scope to cover four core dimensions: performance evaluation indicators of shading technologies, testing methods, energy-saving characteristics, and impacts on architectural design and aesthetics. Research shows that dynamic external shading and comprehensive external shading have significant energy-saving advantages, while internal shading and intermediate shading have wide adaptability. The energy-saving effect of various shading technologies is closely related to climate zone characteristics and component materials. This paper also points out the current deficiencies of shading technologies and looks forward to the future development direction of green low-carbon, intelligent and efficient. This review can provide theoretical support and practical reference for building energy-saving design, shading product research and development, and the formulation of relevant standards, helping the construction industry achieve green and low-carbon transformation.

Research on the Application and Accuracy Improvement of Weld Defect Detection Technology for Steel Structure Bridges

Jing Su — 2026-05-12

To address the issues of insufficient accuracy and susceptibility to multiple factors in the detection of weld defects in steel structure bridges, and to ensure the structural safety and service life of bridges, this paper systematically analyzes the classification and formation mechanisms of weld defects, as well as the core principles of detection technology. It dissects the factors influencing accuracy from four dimensions: equipment, parameters, environmental structure, personnel operation, and data processing. Based on this analysis, a multi-dimensional accuracy improvement plan is designed, encompassing equipment optimization, anti-interference technology, algorithm upgrades, and process standardization. Verification experiments are conducted through the establishment of a simulated test platform. The results indicate that the optimized detection plan enhances the identification accuracy of typical defects such as porosity, slag inclusions, and incomplete penetration to 96.3%, with detection errors controlled within ± 0.12mm. This represents a 21.7% improvement in accuracy compared to traditional methods, providing technical support for the precise detection of weld defects in steel structure bridges.

Research on the Evaluation System for the Revitalization and Utilization of Historical Buildings from the Anti-Japanese War in Chongqing and the Dissemination Path of Digital Study Tours

Yue Yang — 2026-05-12

Against the backdrop of ongoing urban renewal, the dissemination of red culture, and the advancement of smart cultural heritage, the preservation objectives for Chongqing’s anti-Japanese War historical buildings are shifting from “preventing disappearance” to “utilization within preservation and dissemination through utilization.” This paper, starting from the needs of revitalization and utilization, constructs a five-dimensional evaluation framework encompassing “conservation of the original structure, digital fidelity, narrative dissemination, educational transformation, and operational governance.” Furthermore, it proposes a digital study tours product system that connects “heritage sites, online exhibition halls, curriculum resources, research tasks, and urban routes.” By examining two digital model samples from Nanquan, namely Tingquan Building and Kong Garden, this paper discusses the differentiated transformation paths for single-dwelling and compound architectural types in digital study tours. The study posits that the revitalization and utilization of Chongqing’s anti-Japanese War historical buildings should not be equated with general tourism development. Instead, it should be based on authentic preservation, supported by digital archiving and narrative design, and guaranteed by curricular transformation and platform-based governance, thereby facilitating the transformation of historical buildings from static relics into public learning spaces, urban memory nodes, and continuous communication media.

Ruyi Chen — 2026-05-12

Complex interchanges and elevated lifting sections represent critical nodes in the reconstruction and expansion projects of expressways and urban express roads, characterized by the most intricate structures, highest risks, and greatest traffic disruptions. Under conditions of heavy network traffic, limited construction space, frequent structural transitions, and interweaving multi-directional traffic flows, conventional traffic organization methods struggle to ensure both construction safety and network efficiency. To systematically address core challenges such as traffic dispersion, safety management, construction transitions, and network coordination faced during the reconstruction and expansion of complex interchanges and elevated lifting sections, this paper outlines the engineering characteristics and traffic pain points of these projects. It proposes key technologies for traffic organization in both complex interchange reconstruction and elevated lifting section reconstruction, aiming to provide technical references for similar complex node reconstruction projects. These technologies hold significant engineering value in enhancing traffic safety during construction, reducing congestion risks, and ensuring the smooth operation of the road network.

Buckling-Restrained Brace Arrangement in Regular RC Frames Based on Pushover Analysis

Feng Li — 2026-05-12

To improve the seismic performance of existing reinforced concrete (RC) frame structures with insufficient lateral resistance, this study investigates the influence of different buckling-restrained brace (BRB) arrangements on a typical five-story, 4 × 4 bay regular RC frame. Based on the original benchmark model, four retrofit schemes were developed by considering two brace forms, namely single diagonal and chevron braces, and two planar locations, namely mid-bay and end-bay arrangements. Five numerical models, including one unstrengthened structure and four BRB-retrofitted structures, were established in SAP2000 V26 for nonlinear static pushover analysis. Geometric and material nonlinearities were incorporated to simulate the inelastic behavior of beams, columns, and BRBs. Pushover analyses were conducted under uniform and inverted triangular lateral load distributions to evaluate the global seismic performance of the structure. The results indicate that all retrofit schemes significantly enhanced the base shear capacity and deformation capacity of the original frame. Under the uniform load pattern, the maximum base shear capacities of the four strengthened models increased by 295%, 148%, 145%, and 148%, respectively, relative to the original structure. Under the inverted triangular load pattern, the corresponding increases were 232%, 128%, 124%, and 127%, respectively. Among the investigated configurations, the mid-bay single diagonal brace arrangement achieved the most effective improvement in lateral resistance and was identified as the optimal retrofit scheme. These findings demonstrate that mid-bay BRB placement is more effective than end-bay placement for enhancing the seismic performance of regular RC frame structures.
