从两个方面对改善短柱特别是超短柱抗震性能的分体柱技术进行了进一步的试验研究，一是分体柱的隔板材料选择和优化的试验研究，二是分体柱施工工艺的试验研究。

The test results also indicate that separating RC ultra short column into separated columns (shear span to depth ratio higher than 2) by gapping longitudinally at the middle of ultra short column can improve the ductility and deformation capacity of the columns effectively.

不设剪力连接件的SRC超短柱的破坏模式为黏结破坏，与RC超短柱相比，其抗剪承载力和变形能力并无明显提高；设置剪力连接件的SRC超短柱的破坏模式为斜压破坏，其抗剪承载力和变形能力显著提高，但构件的变形能力仍然难以满足现行抗震规范要求。

On the base of the analysis about the cause why this type of systems is hard to be controlled a new FNN, the FNN based on hyper-cylinder clustering, is presented. By comparison with the FNN based on hyper-sphere clustering, for any sample to be clustered, the FNN based on hypercylinder takes not only its input sample but also its output value into consideration. And so it is impossible for any two samples with'close'input samples and'estranged'output values to be clustered in the same cluster.

借助于对非线性系统模型Ⅱ不可逆情形下难以控制原因的分析，提出了基于超柱体聚类的模糊神经网络，与基于超球聚类的模糊神经网络相比，这种模糊神经网络在聚类时不仅考虑样本中的输入向量，也考虑样本的输出值，因此不会将输入向量较接近而输出值差异较大的两个样本聚为一类。
