主　　题：Glulam compression-bending members creep stress level relative eccentricity 

摘      要：Creep test results of glulam members under compression and bending were studied in this *** creep tests were conducted to investigate the influence of the stress level and relative eccentricity on the creep deformation of glulam *** test results showed that the creep deformation trends of glulam members under long-term compression and bending loading were similar;the creep deformation increased with increases in both the stress level and relative ***,the relative creep deformation decreased with the increase in both the stress level and relative eccentricity under long-term loading,and a five-parameter creep model was proposed to analyse the creep mechanism of glulam members under compression and *** good fitness of the test results indicated that the five-parameter model was able to accurately simulate the creep deformation of glulam compression-bending ***,a numerical model was developed using the creep equation,which was related to the parameter a and *** simulation results were in good agreement with the test results,and the parameters a and b were correlated to the relative eccentricity and stress level,*** on the corrected parameters a and b,the relative creep deformation of glulam compression-bending members was predicted over 50 years.
