Spatial patterns and preservation inequality of socialist built heritage in Beijing: a GIS–geodetector analysis (1915–1978)

Abstract Socialist Built Heritage (SBH) represents a crucial part of China’s modern urban memory, embodying the historical legacy and ideological aspirations of the socialist construction era. Yet, amid rapid urbanisation, SBH faces growing threats from redevelopment and policy n...

Shaking table tests of subway station-bridge complex structure to evaluate nonlinear seismic response under strong earthquakes

To investigate the nonlinear seismic performance of subway station-bridge complex structures during strong earthquakes, shake table tests were conducted on specimens consisting of a two-story three span subway station and a three-span variable cross-section steel box girder bridg...

Enhancing Knowledge Management in Green Building Engineering: A Hybrid Retrieval-Augmented Generation Approach to Support Project Assessment

Abstract Green building assessment relies heavily on manual queries of complex engineering regulations, making the introduction of knowledge management theories crucial for improving assessment efficiency. However, the inherent characteristics of engineering regulations—dense ter...

Combined Effect of Courtyard Aspect Ratio and Wind Direction on Natural Ventilation in Educational Buildings Using a Porous-Media CFD Model

Natural ventilation is an important passive strategy for improving the indoor environmental quality of educational buildings. However, ventilation performance in courtyard buildings is strongly influenced by the interaction among building morphology, wind direction, and dense cla...

Major-axis flexural buckling behavior of welded ultra-high-strength steel I-section members

The increasing application of ultra-high-strength steel (UHSS) in high-rise buildings and long-span structures demands a thorough understanding of its structural behavior. This paper presents the systematic study on the major-axis flexural buckling behaviour of Q1100 ultra-high-s...

Prefabricated steel-concrete composite beams with distributed Y-shaped connectors embedded in UHPC: experimental investigation and analytical model

The concept of prefabricated steel-concrete composite beams (PSCCBs) in bridge engineering provides innovative insights into the design of composite beams. To further enhance the interfacial shear behavior and overall flexural performance, improve construction quality, and reduce...

Uncovering Static–Dynamic Interaction Patterns Between Commercial and Residential Spaces Within Beijing’s Sixth Ring Road Using POI and Human Mobility Trajectory Data

Commercial and residential spaces constitute two fundamental components of urban spatial structure, and their coupling relationship critically shapes urban functional organization and planning interventions. However, integrated analyses of static facility layouts and observed hum...

Online coordinated estimation of origin–destination, path, and link flows in urban rail transit networks via a physically constrained computational graph

Urban rail transit (URT) systems require timely estimates of origin–destination (OD) demand and network-wide link flows to support crowding management and disruption response under rapidly changing conditions. Despite the growing availability of multisource data, online estimatio...

A novel fretting fatigue life prediction neural network based on data extended agent model and intense physical constraint

Fretting fatigue is a critical failure mode in mechanically joined structures that severely affects component reliability and safety, making life prediction essential. Due to its highly complex damage mechanisms, traditional prediction methods are limited in accuracy. Although ma...

Optimization of photovoltaic shading angles for net energy and indoor daylighting: a case study in Beijing

Photovoltaic shading devices (PVSDs) have significant potential to reduce building energy consumption and improve indoor daylighting. However, most previous studies have investigated PVSD performance at the single-building scale, while room-specific design and the effects of surr...

From imperial order to urban wilds: spatial fractures and localized drivers of cultural ecosystem services along the Beijing central axis

Linear cultural heritage corridors face increasing risks of spatial fragmentation during rapid urbanization. However, understanding the localized driving mechanisms of CES perception across such vast scales remains a critical challenge for integrating historic conservation with l...

Thermomechanical Fully Coupled Nonorthogonal Elastoplastic Constitutive Model for Concrete

Abstract This study establishes a thermomechanical fully coupled nonorthogonal elastoplastic model, grounded in thermodynamic principles, to capture concrete’s strength degradation, plastic strain accumulation, and temperature-enhanced dilatancy under thermomechanical coupling. T...

Coupled socio-ecological feedback mechanisms driving rocky desertification in karst peak-cluster depressions: a system dynamics and scenario analysis approach

Karst peak-cluster depressions are among the most fragile socio-ecological systems, where rocky desertification is shaped by both ecological vulnerability and intensive human disturbance. However, the long-term feedback mechanisms linking socioeconomic development, energy consump...
