Aiming at the seismic design requirement of "strong column-weak beam" frame structure and combined with test data analysis and computer simulation, the influence of slab bar participation on inelastic response and the yielding-damage mechanism of frame structure have been investigated. Two design schemes that considering the slab bars or neglecting the slab bars were respectively applied to an example frame building to compare the damage situations, which were simulated by the nonlinear time history analysis program SARCF (Seismic Analysis of Reinforced Concrete Frames). The research indicated that slab bars in the tensile zone have a direct enhancing action on the capacity of the frame beam resisting negative moment, which will increase with the augmentation of the monolithic deformation of the beam-slab member. The effect of slab bar participation will develop adequately after the peak ground acceleration acting on the structure reaches the level of design basic acceleration of ground motion. The design method neglecting the slab bars will underestimate the actual flexural strength of the frame beam, which will result in a change of seismic behavior of the structure from "strong column-weak beam" to "strong beam-weak column", and the probability of the change will increase with the augmentation of earthquake action.

The composite shear wall is the core component of the thermal insulation integrated structure, which is a load-bearing shear wall with good thermal insulation, sound insulation, and seismic resistance. To improve the applicable height of the composite shear wall structure, a cohesive sandwich heat-insulation composite shear wall with door frame inclined tendon and diamond-shaped inclined tendon is proposed, and the quasistatic force of four 1/2-scale shear wall test specimens is carried out. Different specimens are analyzed, including failure modes, hysteresis curves, skeleton curves, stiffness degradation, ductility performance, and energy dissipation capacity. The following conclusions are drawn: the failure modes of the specimens are bending and shear failure; the ultimate strength and deformation performance of the composite wall close to the solid wall; the composite wall with the door frame inclined tendon can effectively delay the wall cracking and improve the bearing capacity and energy consumption capacity of the composite wall; the configuration of the diamond-shaped inclined tendon improves the ductility and energy dissipation capacity of the composite wall.
