針對921集集大地震建築物結構之樑柱嚴重破壞,發掘地震力破壞起始點,深入了解RC結構與SRC結構建築的差異性。對於地震的耐震程度尋求解決之道,研發C形鋼+抓漿網在SRC的耐震結構,依據過去現場實作經驗不斷修正改良。
在潘誠平教授指導下以C 型鋼、抓漿網、H鋼300mm*200mm,澆灌混凝土組裝鋼梁:300mm *250mm*3000mm與300mm*250mm*3400mm共兩支。使用C型鋼、抓漿網、H鋼300mm*300mm澆灌混凝土,組裝直柱500mm*500mm*3000m一支,分別送入台灣科技大學結構實驗室。由呂冠群先生操作500噸的油壓機,吳昱豪同學操作電腦,進行試壓鋼梁桿件正向2分之1、反向4分之1、正向4分之1 ,觀察受軸壓力的降伏點,桿件產生位移,彎距,剪力的力學行為。直柱500mm *500mm之站立軸壓超過700噸壓不壞(油壓機只有500噸),只能橫躺跟鋼梁一樣,強軸2分之1、強軸4分之1、弱軸4分之1做測試。
測試後的結果能與手算的數據做比較,求出較接近實驗結果運算的公式,直柱、橫梁、剪力牆加上鋼承板施工法,期望能大力推廣較安全的SRC結構建築取代RC建築。
Several beams of the buildings were destroid during the 921 Earthquake. It was the starting point to explore the seismic forces of it. The undersanding of the difference RC-depth structure and SRC structure was very important. Based on real live experience from the correctment and improvment we seek for a way to resolve the earthquake seismic degree by development of the C-shaped Steel and Slurry Grasp Reticulum in the SRC structure.
From the instruction of Professor Pan Chengping we did two experiments. First use C-shaped Steel and Slurry Grasp Reticulum with H steel specification 300mm * 200mm and then pour concret to assemble two steel beams with specification 300mm *250mm*3000mm and 300mm*250mm*3400mm. Second we use of C-shaped Steel and Slurry Grasp Reticulum with H steel specification 300mm * 300mm and then pour concret to assemble Straight pillar steel with specification 500mm * 500mm * 3000mm. The experiments were done at National Taiwan University of Science and Technology’s Structure Laboratory and was operated by Mr. Lu Guanqun with the 500 tons hydraulic pressing machine and Mr.Wu Yu Hao with the computer. The first experiment is the pressure test on the two steel beams conducting Forward 1/2、Reverse 1/4、Forward 1/4 and observe the yield point of view of the shaft pressure Bars to see how much displacement, bending moments and shear mechanical behavior has changed. The second experiment is the vertical stand pressure test on the Straight pillar steel 500mm * 500mm. The Straight pillar steel can withstand more than 700 ton of pressure. But because the hydraulic pressing machine could only press 500 tons so the testing was done as same as steel beam conducting Strong shaft1/ 2、strong axis1/4 and weak axis 1/4 for testing.
The data comparison from test results and hand calculations makes the experimental result’s formula closer to obtained operation. We are hoping to promote this safer SRC structure building to replace RC one by Uprights, beams, shear walls coupled with steel plate construction method.
