Abstract Research purposes: Rigid bracing domes are a new type of prestressed spatial structures，many construction technology challenges of cable domes are overcome by it. The structure has characteristics of easy node location， high efficiency，the support from the balance and so on. According to characteristics of rigid bracing dome，the construction method was proposed from the engineering view，and then simulation analysis strategies and procedures for implementation were given.
Research conclusions:(1)The method is that rods are installed in accordance with the order of nodes and then the system are enhanced the overall and tensioned. Construction control and monitoring methods were given.(2)The construction process was simulated by the improved dynamic relaxation method. Implementation strategy was given. Program was programmed by using FORTRAN language and ANSYS APDL language.(3)Numerical example shows that super-tensioned problem can be effectively reduced through the proposed construction and installation methods. (4) References to the construction and analysis are provided by the results for practical engineering of rigid bracing dome.
