Floor plan segmentation is a foundational step for tasks such as surface area estimation and three‐dimensional building reconstruction.

We introduce a novel multibranch and multiattention framework for deep floor plan segmentation, explicitly designed to handle the challenges of interclass similarity, ambiguous room boundaries, and diverse architectural styles. Our method leverages intrabranch channel attention and cross‐branch positional attention to refine both boundary recognition and room‐type segmentation, significantly enhancing robustness and accuracy across multiple datasets.

Inverting earth pressures from observable structural responses, such as deformation data, holds promise. However, existing methods often rely on presumptions about pressure complexity, which can be infeasible for many poorly performing in‐service infrastructures. This paper proposes a trans‐dimensional Bayesian method that simultaneously infers both the complexity and magnitude of earth pressures by parameterizing a set of a priori unknown variables, where the exact number of parameters remains undetermined. A Bayesian framework is employed to represent the posterior distribution of these parameters, with a trans‐dimensional Markov chain specifically designed for statistical inference of the distributed pressures. Case studies demonstrate that the proposed method outperforms traditional methods, which are limited by rigid presumptions. Furthermore, it is shown that the inferred pressures can reproduce comprehensive structural responses, such as internal forces, providing new tools and insights for structural health monitoring of underground infrastructures.","PeriodicalId":156,"journal":{"name":"Computer-Aided Civil and Infrastructure Engineering","volume":"106 1","pages":""},"PeriodicalIF":11.775,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144684620","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compared to wind tunnel measurements, the simulated mean <jats:italic>C<jats:sub>p</jats:sub></jats:italic> is well predicted, and the variation in inflow turbulence has a negligible effect. The rms <jats:italic>C<jats:sub>p</jats:sub></jats:italic> increases with increasing turbulence intensities and increasing turbulence length scales.

A three-dimensional (3D) track model is developed using finite element-based Euler–Bernoulli beam formulations for rails, dynamic force inputs, and nonlinear interactions at the sleeper–ballast interface to capture dynamic buckling behavior. To address computational challenges in simulating extended track sections, the framework employs message passing interface–based parallelization, optimizing load balancing, and minimizing interprocess communication overhead. Unlike approaches that simulate long tracks virtually by recycling a small domain, the proposed method maintains complete dynamic and structural detail across the entire track length. It dynamically adjusts lateral rail stiffness and incorporates thermal compression effects to enable simulation of buckling behavior, while efficiently scaling across high-performance computing clusters. Case studies demonstrate the framework's ability to simulate large-scale tracks under combined thermal gradients and dynamic train loads, achieving near-linear speedup and reducing runtime by up to 90% compared to serial approaches. Additionally, a machine learning–based buckling risk assessment is presented as a use case, where a model trained on long-track simulation results predicts buckling risk across extended sections.

This decomposition process can introduce uncertainties in the results. Additionally, employing vehicles is logistically impractical for most footbridges. To overcome these issues, this paper proposes a new, practical framework using computer vision to measure DILs/DISs on footbridges. It combines a stationary pedestrian loading strategy with a computer vision input–output wireless sensor network (CVIO‐WSN). This framework has two main features: (1) pedestrians follow the “step‐and‐stand” rule, and their weight acts as a static load when they stand still at discrete locations across the footbridge for DIL/DIS measurement; (2) CVIO‐WSN consists of input nodes for human load localization and output nodes for simultaneous structural response measurement, allowing load and response data to be collected in a contactless way that minimizes disruption to operational structures. Two laboratory experiments were conducted to validate this system. The first evaluated the timestamping accuracy between two identical sensor nodes tracking the same moving target, showing an average synchronization error of 2.39 ms. The second assessed the localization accuracy of the input nodes, with the average error of 14.0 mm on the X‐axis and 16.9 mm on the Y‐axis. The method was then applied to an experimental floor structure and an operational full‐scale footbridge. In the first application, the input nodes tracked a human through a sequence of 77 locations across the floor, while the output node measured structural displacement at the center, successfully obtaining the structural DIS. In the second application, the method localized four humans (pedestrians) moving to discrete locations across an operational arch footbridge and briefly remaining stationary while measuring displacement at two points of the structure. Although the measurement results were promising, using heavier pedestrians or increasing their number is recommended to improve the signal‐to‐noise ratio of the structural displacement measurements.","PeriodicalId":156,"journal":{"name":"Computer-Aided Civil and Infrastructure Engineering","volume":"9 1","pages":""},"PeriodicalIF":11.775,"publicationDate":"2025-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144611156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, current in situ building damage assessment is primarily conducted through visual inspections by engineering professionals and deep learning techniques using single‐modal information, which are time‐consuming and unable to effectively integrate visual and textual information. In recent years, multimodal learning methods and large language models (LLMs), which could process visual and linguistic information, have emerged as viable alternatives for damage assessment of building constructions. In this study, a vision question–answering model for structural damage assessment (SDA‐Chat) is developed that automatically generates professional textual interpretations of structural damage images via multi‐round visual question–answering (VQA) interactions. A three‐stage training strategy that includes instruction fine‐tuning is designed to improve the model's VQA accuracy. The cross‐modality projector based on dimension reshaping and parallel network architecture is developed to enhance the accuracy and speed of alignment of multimodal features. Comparative experiments are conducted on the self‐constructed dataset containing 8195 pairs of structural damage images and corresponding damage description texts, focusing on various advanced LLMs. The results highlight that the SDA‐Chat can simultaneously process seven different tasks, demonstrating the effectiveness of the proposed method.
