Method for improving performance of masonry cultural relic building structure
The invention discloses a masonry cultural relic building structure performance improvement method, which comprises the following steps: step 1, carrying out anti-seismic performance evaluation, and estimating a generated maximum interlayer displacement value D; 2, preliminarily constructing an anti-seismic structure, and arranging the mounting positions of an inner supporting frame and an outer inhaul cable; 3, designing an inner support frame, and carrying out design calculation on the cross section; 4, verifying and calculating the inner support frame, and calculating a stress ratio limit value Rlim it; fifthly, outer inhaul cables are designed, the number of the outer inhaul cables is two, and the diameter d of the outer inhaul cables does not exceed 20 mm; sixthly, simulation analysis calculation is conducted on the anti-seismic structure, and a finite element model is built; and step 7, performing post-processing on a simulation analysis calculation result, and comparing the maximum interlayer displacement dmax with the maximum interlayer displacement value D. According to the method, under the condition that an original cultural relic building is not damaged, the anti-seismic capacity is improved, the displacement of the structure under the earthquake effect is effectively reduced, the force transmission path of the original structure is not changed, the stability of the building is enhanced, and the application prospect is wide.
本发明公开了一种砖石质文物建筑结构性能提升方法，包括以下步骤：步骤一，抗震性能评估，预估产生的最大层间位移值D；步骤二，抗震结构的初步搭建，布置内支撑框架和外拉索的安装位置；步骤三，内支撑框架设计，对截面进行设计计算；步骤四，对内支撑框架验证计算，计算应力比限值Rlim it；步骤五，外拉索设计，外拉索设置两根，直径d不超过20mm；步骤六，抗震结构的仿真分析计算，搭建有限元模型；步骤七，仿真分析计算结果后处理，将最大层间位移dmax与最大层间位移值D进行对比。该方法在不破坏原有文物建筑的情况下提高了其抗震能力，有效降低结构在地震作用下的位移，且不改变原结构的传力路径，增强建构的稳定性，应用前景广。
