3.2a：考察结点C、D、E、I、K、L，这些结点均为T 型结点，且没有荷载作用，故杆件CG、DJ、EH、IJ、KH、LF均为零杆。考察结点G 和 H，这两个结点上的两竖向链杆均已判断为零杆，故这两个结点的受力也已成为T 型结点的情形 由于没有荷载作用，故杆件AG、BH 也为零杆。整个结构共有8根零杆如图3.2c 虚线所示。图 3.2b：考察结点D，为“K”型结点且无荷载作用，故；对称结构对称荷载（A 支座处的水平反力为零），有，故杆件 DE 和 DF 必为零杆。文档编码:CL2Y2W7L10R2 HQ6J7M1V6D7 ZA5H8P8S10A1文档编码:CL2Y2W7L10R2 HQ6J7M1V6D7 ZA5H8P8S10A1文档编码:CL2Y2W7L10R2 HQ6J7M1V6D7

F，由于 DE、DF 已判断为零杆故杆件AE、BF 也是零杆。整个结构共有四根零杆。如图3.2d 虚线所示。3.图 3.3a 三铰拱为抛物线型，轴线方程为，试求截面K 的内力。图 3.3 分析：结构为一主附结构：三铰拱ACB 为基本部分，CD 和 CE 分别为附属部分。内力分析时先求出附属部分在铰C 处的反力，再对三铰拱进行分析。对附局部分CD、CE 的计算相当于对两个简支梁的计算，在铰C 处只产生竖向反力。这样基本部分三铰拱的计算就转化为在铰C 作用竖向集中力。解：（1）附属部分CD 和 CE。CD 和 CE 相当于 C 端支于三铰拱的简支梁，故C 处竖向反力为，（）文档编码:CL2Y2W7L10R2 HQ6J7M1V6D7 ZA5H8P8S10A1文档编码:CL2Y2W7L10R2 HQ6J7M1V6D7 ZA5H8P8S10A1文档编码:CL2Y2W7L10R2
