Abstract
Official abstract text for this publication.
A method for manufacturing a non-magnetic spatial latticed shell structure composed of carbon fiber plate members. The load-bearing member of the latticed shell structure is made of non-magnetic carbon fiber plate, and joints are made of non-magnetic titanium alloy material. The magnetic shielding layer is provided on the roofing system above the structural layer, and a non-magnetic space with a magnetic field strength lower than 1 nT is formed inside the structure. The load-bearing members are fixed by two carbon fiber limb plates in the form of inter-limb connection and forms an hollow rectangular built-up section; and the joint comprises a titanium alloy gusset plate, a titanium alloy bolt group, and a carbon fiber limb plate; the magnetic shielding layer of the roofing system comprises a shielding layer pad, a shielding layer, a shielding laminate, a buffer layer, a permalloy plate, and a batten.

What is claimed is: 1. A method for manufacturing a non-magnetic spatial latticed shell structure composed of carbon fiber plate members, wherein load-bearing members of the non-magnetic spatial latticed shell structure are made of non-magnetic carbon fiber plates, and a joint of the non-magnetic spatial latticed shell structure is made of a non-magnetic titanium alloy material, a magnetic shielding layer is provided on a roofing system above a structural layer, and a non-magnetic space with a magnetic field strength lower than 1 nT is formed inside the non-magnetic spatial latticed shell structure. 2. The method for manufacturing the non-magnetic spatial latticed shell structure composed of the carbon fiber plate members according to claim 1 , wherein the non-magnetic spatial latticed shell structure uses carbon fiber double-limb plate members as the main load-bearing members, and the carbon fiber double-limb plate members are manufactured by a following method: arranging two carbon fiber limb plates with a length of l, a thickness of t and a width of b in parallel at a distance h, and fixing the carbon fiber limb plates at an interval of d by inter-limb connections, thereby forming a hollow rectangular cross-section built-up member, wherein equivalent slenderness ratios for internal force verification are calculated as follows: weak axis slenderness ratio : λ h y = α g α t 2 3 2 l 2 t ( 2 t + h ) 3 + d 2 t 2 strong axis slenderness ratio : λ h x = 2 3 b where α g represents a reduction factor related to a geometric size of the carbon fiber limb plate, and is to be determined based on an axial compression test of a double-limb spliced carbon fiber plate; and α t represents a reduction factor related to an interlaminar shear strength of the carbon fiber limb plate, and needs to be determined based on the axial compression test of the double-limb spliced carbon fiber plate. 3. The method for manufacturing the non-magnetic spatial latticed shell structure composed of the carbon fiber plate members according to claim 1 , wherein the joint comprises a cross-shaped titanium alloy plate, a titanium alloy bolt group and a carbon fiber limb plate, and is manufactured by a following method: fixing the carbon fiber limb plate and the cross-shaped titanium alloy plate using the titanium alloy bolt group in a frictional connection manner to form a titanium alloy joint, wherein a failure process of the titanium alloy joint when subjected to a moment load presents four stages of bonding-sliding-strengthening-failure, and wherein a joint rotation stiffness in the sliding and failure stages is relatively weak, and a joint rotation stiffness K 1 in the bonding stage and a joint rotation stiffness a joint rotation stiffness in the strengthening stage are designed and calculated as follows: K 1 = Et j b j 3 12 l j K 3 = 1 12 l j Et j b j 3 + ( d b t ) 2 (
