With the emergence of Industry 4.0 era in China, more refined methods are being proposed for healthy living requirements human settlements. Since rural settlements China relatively backward, this study aimed to investigate influencing factors health. First, through field surveys and questionnaires conducted with villagers Xiangxi’s traditional villages Hunan Province, we analyzed affecting health qualitatively quantitatively using SPSS software. We identified three main dimensions including...

Under the macro context of severe global aging, typical villages and dwellings Miao ethnic group in western Hunan were selected, daily life health status local elderly evaluated through behavioral observation, interviews, questionnaires (e.g., physiological, psychological, residential environments). In addition, relevant evaluation factors respondents correlated then analyzed using SPSS software. As indicated by results this study, used all spaces functions existing satisfied with except for...

The horizontal press performance of column is deteriorated because its special-shaped section. Moreover, the antiseismic worse, only used in regions where seismic intensity lower. So main problem to enhance ductility and shear capacity. This test study on mechanical has been carried out through 14 SRCLSSC 2 RCLSSC. focuses impacts axial load ratio (n t ), hooped reinforcement (ρ v span (λ) steel ss ) strength SRCLSSC. It can be concluded that increasing with n ρ , but degree small when a...

This study aimed to investigate the static performance of notched hexagonal concrete‐filled steel tube (CFST) stub columns through axial loading. Notch length, notch location, and direction in 14 CFST were experimentally studied. Stress process, failure mechanism, ultimate strength analyzed. Results show that notches tubes can weaken restraining effect pipes on core concrete induce a decrease specimens. The mode components is greatly affected by orientation. closed under compression...

The horizontal press performance of column is deteriorated because special-shaped section. Moreover, the antiseismic columns worse, it only used in regions where seismic intensity lower. So main problem to enhance ductility. This test study on mechanical has been carried out through fourteen SRCTSSC and RCTSSC. focuses impact axial pressure ratio(nt), hooped reinforcement ratio(ρv), shear span ratio(λ) steel ratio(ρss) strength SRCTSSC. It can be concluded that increasing with nt ρss , but...

Intergenerational sharing promotes social cohesion within communities by encouraging dialogue and understanding across different age groups. Nevertheless, existing research has inadequately delved into the human experiences meaning-making processes that underpin intergenerational sharing, leading to a limited grasp of effective design intervention strategies in community spaces. This study aimed explore environmental factors influencing interactions public spaces Changsha, China, addressing...

Compared with reinforced concrete shaped columns, bearing capacity and ductility of steel columns are significantly improved, so it is theoretical significance practical application value to research. Based on the plain cross section presume, material T-section boundary calculation unit, 15 T-shaped columns(SRCTSC) have made nonlinear full-rang numerical analysis. It demonstrates that most adverse curvature load angle SRCCRSC 180°.Loading ( ), axial compression ratio spacing diameter...

Attack of sulfate crystallization and chemical interaction between hydration product is one the most important factors responsible for degradation cementitious materials. This study investigates effects emulsified asphalt fly ash as well their combination on resistance mortar to physicochemical attack in order develop high performance materials with attack. The partly-submerged experiment 5% Na2SO4 solution designed simulate salt sample. Results indicate that, compared ash, addition more...

An extensive research programme was set up to investigate the efficiency of scrap rubber particles on strength cementitious materials. The index loss rate paste and mortar sample caused by increasing 1% volume proposed analyze in And corresponding mechanism also discussed this paper. Results indicate that investigated area, compressive both for almost ranges from 2% 5% depending total particle added into sample. However, flexural is obviously different that. Three roles played materials,...

This paper focuses on improving the flexural behavior of steel fiber-reinforced beams with continuously graded structure. Successive vibrating after casting is assumed to be a feasible way produce (GFRBs), resulting in fibers purposefully distributed tensile region. The fiber orientation and distribution are quantified through X-ray computed tomography (XCT). porosity pore size evaluated basis XCT images mercury intrusion porosimetry. Influences re-arrangement microstructure compressive...

Abstract A method of “concealed corbel angle steel and bolt” is proposed to connect beams columns assembled frame. To study the seismic performance connection designed an ordinary concrete beam specimen three in form assembly specimens. The hysteretic curve, skeleton curve ductility coefficient cast-in-place with concealed are analysed by low cycle repeated load test. influence thickness additional rib on scheme discussed. test results show that: compared specimens, specimens have higher...

To improve the ductility of high-strength concrete and enhance load-bearing capacity steel reinforced (SRHSC) columns, fibers were added to SRHSC prepare fiber (SSFRHSC) columns. In order study eccentric compression SSFRHSC based on experimental finite element model specimens columns established using ABAQUS software, accuracy was verified by combining test results. On basis experiments, parameters such as volume rate, strength eccentricity distance further changed extend study. The results...

Prefabricated construction is a structural form vigorously developed by the country and inevitable path for sustainable development of industry. In order to enhance seismic performance prefabricated concrete frame structures, concealed steel angle connections beams columns are employed. Based on experimental research force these connection nodes, finite element model node established using ABAQUS software analyze influence design parameters specimen.
