Calculation model for section strength of moisture-proof layer of wooden building envelope near water area.

The dampness of building envelopes not only poses a great threat to the use and safety of building structures, but also the long-term dampness will affect the aesthetics of the building maintenance structure and even the degradation of indoor air quality, so it is more vulnerable to the offshore. The calculation and simulation of the section strength of the moisture barrier layer of the building envelope structure are of great significance. Based on the analysis of previous research results, this paper takes a moisture-proof layer of wedge-shaped envelope structure as an example, establishes a finite element model through simulation software, simulates the stress loading process and analyzes the stress-strain curve; in the study of steel bar size and steel type After the influence of parameters such as hoop index, concrete strength, water-cement ratio, and reinforcement ratio on the section strength of the moisture-proof layer, combined with the non-linear least-squares method, the shear resistance, bending resistance and compression resistance of the moisture-proof layer of the envelope structure are analyzed, a multi-factor calculation model of strength established. The validity of the model is verified by comparison with experimental data, and it provides a reference for further research. [ABSTRACT FROM AUTHOR]
