Abstract:
An analytical procedure to generate reinforced concrete plane frame response to reversing static loading is developed. Yield is permitted to occur and spread to crossections which are not predetermined. Response of a 3 story 2 bay frame under reversed lateral load is investigated with particular reference to locations that yield, propagation of yield, beam and column behavior and collapse. To permit the structure prescribe its locations of inelasticity rather than predetermining these regions was observed to be a significant aspect in mathematical modelling.

This paper presents briefly the methodology and summarizes the results of ananalytical investigation of the dynamic inelastic response of isolated reinforced concrete structural walls to earthquake motions. Considered in particular is the distribution of inertial forces along the height of the struc-ture. Results of the analyses are compared with the design force distributions specified by the Uniform Building Code (UBC) and Applied Technology Council (ATC). Suggested modifications to the code force distributions, as these apply to isolated structural walls, are presented.

The results of lateral load tests on one third scale slab-column structures with realistic boundary conditions are presented. Measured moments at both internal and edge columns are compared with predictions based on methods in codes and other analytical procedures including finite elements. For all methods of prediction the lateral stiffness of the frameworks is overestimated and in some cases to a substantial extent. The lateral stiffness was also found to be influenced by cracking due to gravity loading.

The results of an experimental investigation to determine strength of rectangular low-rise structural walls for buildings are presented in this report. Seven large specimens with "height-to-hori-zontal- length" ratios of 1.0 were subjected to static in-plane horizontal loads. One of the specimens was subjected to ten cycles of load reversals. Variables in the test program were amount and distribution ofvertical and horizontal reinforcement. The walls did not have any boundary elements or special hoop reinforcement. No vertical load was applied. Results indicate that low-rise rectangular walls can develop shear stresses on the order of 10 f'c psi (0.83 f'c MPa). Also, results indicate that shear strengths implied by Section 11.10, Special Provisions for Walls, of the 1977 ACI Building Code provide a reasonable lower bound capacity, even when load reversals are applied.

Results of an experimental investigation to determine inelastic load-deformation character istics of reinforced concrete structural walls are reported. Sixteen large structural walls have been tested. These tests show that structural walls possess signif icant rotational ductility when subjected to reversing loads. In addition, it was found that shear distortions within the hinging region of a wall are coupled to flexural rotations. Therefore, inelastic shear distortions should be considered in structures designed to utilize the inelastic capacity of struc-tural walls for earthquake resistant construction.
