| 采用正交试验设计方法，考虑框支梁高跨比( h b/ l 0)、抗震墙截面宽度与高度比( B w/ H w)、密肋复合墙高跨比( h w/ l 0)，通过对框支-斜交密肋复合墙结构计算结果直观分析和方差分析，对构件关键部位内力和整体结构最大转角影响因素进行显著性分析，得出 h b/ l 0和 B w/ H w对框支梁和框支柱的部分内力具有显著影响，对整体结构最大转角具有一定影响的结论．并在此基础上给出相应框支梁内力系数实用设计计算方法． |
| 英文摘要: |
| Considering the factors of height-to-span ratio ( h b/ l 0) of the beam, width-to-height ratio ( B w/ H w) of the aseismic wall and height-to-span ratio( h w/ l 0) of multi-ribbed composite wall(MCW), the orthogonal test design method was adopted to analyze the calculation results of frame-supported oblique-grid MCW structure by using the visual and variance analyses, and the internal force influence factors of key parts and structural maximum angle were also researched. It is concluded that h b/ l 0 and B w/ H w have significant effects on part internal force of frame-supported beam and frame-supported column, as well as have certain effects on structural maximum angle, and based on the analytical results, the calculation method on internal force coefficient of frame-supported beam is obtained. |
