Damage Localization Of Simp Ly Supported Beams Based On Deflection Influence Surfaces Calculated By Three-Dimensional Boundary Face Method, Yin Xinfeng, Luo Zonghao, Yan Wanli, Kaiersaer ∙Tuerdi

Journal of China & Foreign Highway

The deflection influence surface (DIS) of a spatial structure is difficult to calculate using the existing two-dimensional boundary element method.To address this issue,a damage localization method based on DIS calculated using the three-dimensional boundary face method (BFM ) was proposed.A custom BFM program with an internal loop was developed,and the internal forces and deformations of a square plate and a supported T-beam structure were calculated using the static method.By specifying the domain of the order of a bivariate polynomial function (BPF ),a secondary optimization program for influence surfaces was established,and the DIS with the minimum mean square error was obtained.The …

As a cement-based composite material with excellent mechanical properties,ultra-high performance concrete (UHPC ) demonstrates outstanding performance in tensile and compressive strength,durability,and impermeability.This material is suitable for the reinforcement and repair of normal concrete (NC) bridge structures.To study the shear behavior of the UHPC-NC bonding interface and its reinforcement effect,this paper conducted interface shear tests using Z-shaped specimens and designed a total of six sets of comparative specimens.The influence of parameters such as the planted bar ratio,implantation depth,and bonding surface size on the shear strength was explored.Through experiments,the load –slip curve and the shear strength data were obtained.The results show that:① …

Field Measurement And Analysis Of Wind Characteristics At Xuefenghu Bridge Site, Yu Wenhao, Yi Lu

Journal of China & Foreign Highway

Wind field parameters at bridge sites serve as an important basis for wind-resistant bridge design.The terrain surrounding the Xuefenghu Bridge is unique-mountains flank both sides in the bridge-aligned direction,and the bridge spans the wide surface of the Zhexi Reservoir.In order to investigate the wind field characteristics under such complex topographic conditions,an observation,acquisition,and wireless data transmission system was established at the bridge site.A one-year in-situ wind measurement campaign was conducted,and the characteristics of average wind and fluctuating wind were deeply analyzed.The results show that the average wind speed at the bridge site generally follows a Weibull distribution,and the average wind direction …

Experimental Study On Shear Resistance Of Existing Prestressed Concrete Hollow Slabs, Lu Youfu, Di Jin, Qin Fengjiang, Sun Yifei

Journal of China & Foreign Highway

Prestressed concrete hollow slabs are widely used in small- and medium-sized span highway bridges in China.With the increase in load ratings,many hollow slab bridges built in early periods fail to meet the current specifications for shear bearing capacity.Nevertheless,these hollow slabs continue to function adequately under existing vehicle loads,making it essential to conduct an in-depth investigation into their shear bearing capacity.Shear bearing capacity tests were conducted on five 16 m-span hollow slabs dismantled from a renovation and expansion project,including three top slabs with a 15 cm cast-in-place concrete structural layer.Various parameters,such as load-displacement curves,web concrete strain,cracking loads,crack development patterns,failure modes,and ultimate …

Research On Automatic Review Method Of Highway Bim Based On Knowledge Graph, Wang Wuyu, Shao Kebo, Zhang Feng

Journal of China & Foreign Highway

Building information modeling (BIM ),characterized by multi-dimensional modeling and multi-source data integration,is becoming a key technology to promote the innovation and digital transformation of the highway design industry.Taking BIM as the design deliverable is an inevitable trend in the future development of highway engineering design.However,the current highway BIM review is mainly conducted manually,which brings about problems such as low efficiency,susceptibility to errors,and high subjectivity.This makes it difficult to adapt to the review requirements of the three-dimensional (3D) digital design mode.To this end,this study proposed an automatic review method of highway BIM based on a knowledge graph.By constructing the knowledge graph …

Walking Each Other Home: A Social Work Portfolio Of Healing, Justice, And Becoming, Serah Lander

Graduate Student Portfolios, Professional Papers, and Capstone Projects

Abstract

This portfolio documents the integration of lived experience, academic training, and professional practice in the pursuit of a Master of Social Work (MSW) degree. Grounded in a personal history shaped by chronic illness, solo motherhood, and economic precarity, this work reframes individual challenges as symptoms of structural neglect and systemic inequity. Through reflective narrative, I explore identity development across intersecting contexts—white, queer, neurodivergent, Jewish by choice, and chronically ill—connecting personal transformation to professional readiness.

Section I: Living the Questions chronicles my evolution from navigating institutional barriers to becoming a systems thinker, crisis counselor, policy advocate, and coalition leader. This …

Challenges And Opportunities In Medical Tourism, Nizar Zein

Visions in Leisure and Business

Medical tourism is a rapidly expanding industry, with an increasing number of patients traveling abroad for medical treatments and procedures. This trend is expected to continue as the industry evolves to meet shifting patient demands and preferences. People are motivated to seek healthcare outside their home countries for various reasons, such as access to advanced technology, faster treatment, higher quality care, or more affordable options available in the destination country. Patients today are more informed and selective about their healthcare choices. They seek not only cost-effective treatments but also high-quality care and an exceptional patient experience. The future of medical …

The Spoon In The Sand: Cripping The Adventure Narrative To Reclaim Autonomy, Maggie Morehart, Fang Wang

Visions in Leisure and Business

Disabled and chronically ill adventure travel - and the digital storytelling that accompanies it - can act as both a deeply personal and a political statement that resides at the intersection of empowerment, rebellion, and performative pressure. Platforms like Instagram amplify the narrative of overcoming, while shifting perceptions of what disabled adventure looks like. These narratives simultaneously have the potential to challenge stereotypes or reinforce unrealistic expectations of disabled bodies. This paper explores the value of adventure and its portrayal as a means of asserting independence, pushing limits, and reclaiming agency in an ableist world.
