摘要
A post-tensioned prestressed assembly-style system of a concrete framework and shock-resistant and energy-dissipating components, and a construction method. The system of concrete framework and shock-resistant and energy-dissipating components comprises a foundation (1), framework columns (2), stacked main beams (4), shock-resistant and energy-dissipating components, and stacked floor slabs (5). The framework columns (2) are in a layered distribution, concrete connecting layers (10) are cast between vertically adjacent layers of framework columns (2). The stacked main beams (4) comprise precast concrete main beams (4.1) and main beam concrete stacked layers (4.2). The stacked floor slabs (5) comprise precast hollow slabs (5.1) and floor concrete stacked layers (5.2) cast in place on top of the precast hollow slabs (5.1). Prestressed steel wire bundles (7) are post-tensioned prestressed steel wire bundles, comprising prestressed steel wire bundle bonded sections (7.1) and prestressed steel wire bundle non-bonded sections (7.2). The prestressed steel wire bundle bonded sections (7.1) are provided at the mid-span part of each precast concrete main beam (4.1) and are 2 m to 3 m in length. The system solves the technical problem of great difficulty in transport and lifting, low structural robustness performance, a large amount of wet work, high post-shock repair costs for column feet, and high costs and complex production for providing energy-dissipating reinforcing bars within beams of an existing structural system.
