Background Lawyer is one of the most stressful jobs, but lawyers' occupational stress is rather under-researched in China. Previous studies have shown that occupational stress and mental health are related to self-regulatory fatigue and health literacy in lawyers, but there is a lack of research on their interaction mechanism. Objective To explore the association of occupational stress and mental health in lawyers and the internal mechanism of action of self-regulatory fatigue and health literacy between them. Methods A convenience sample of 660 lawyers from 7 leading Chinese law firms were surveyed from May to June 2022 using questionnaires including a self-compiled Demographic Questionnaire, the Lawyers' Occupational Stress Scale, Symptom Checklist-90 (SCL-90), Self-regulatory Fatigue Scale (SRF-S) and National Residents' Health Literacy Surveillance Rapid Assessment Questionnaire (HLSRAQ). Stepwise regression was used to explore the mediating effect of self-regulatory fatigue between occupational stress and mental health, and bootstrap method was used to test the mediating effect of self-regulatory fatigue. Model 5 in PROCESS 3.4 was used to explore the moderated mediating effect of health literacy between occupational stress and mental health. Bootstrap method was used to test the moderating mediating effect of health literacy, and further simple slope test was used to test the moderating effect, and the effects of occupational stress on the mental health of lawyers with different health literacy levels were analyzed. Results Six hundred and fifty-six cases (99.39%) who effectively responded to the survey were included for final analysis. The average scores of occupational stress, SCL-90, SRF-S and HLSRAQ were (106.9±34.8), 39.0 (15.0, 84.0), (39.4±10.0) and (13.9±3.7), respectively. Stepwise regression analysis showed that occupational stress could positively predict mental health (β=0.36, t=13.40, P

Experimental testing was conducted on a two-story single bay semi-rigid steel frame with multi-ribbed grid composite steel plate shear wall specimen, under quasi-static loading, to research its seismic performance. The interaction between the wall plate and the surrounding frame and failure model were investigated with regard to the load-carrying capacity, ductility, stiffness and energy dissipation capacity. Experimental result indicates that the structure resists the lateral loads by shear action of the wall plate in the elastic stage and when in the inelastic stage the resistance is provided by the tension zone which arises in the buckled wall plate. The multi-ribbed grids limit the out of plane deformation of wall plate, increase the initial stiffness, avoid the pinch shrinkage of the hysteresis loop, reduce the noise and vibration of steel plate and significantly improve the energy dissipation capacity and safety margin. The surrounding frame cooperates with the wall plate in resisting the lateral loads, and the structure exhibits stable behavior at very large deformation. The primary inelastic damage mode is the yielding and tearing in tension zone of the infill plates combined with the surrounding frame beam and column yielding. [ABSTRACT FROM AUTHOR]
