Precast Walls

Precast wall-slab-wall buildings can be found in many different earthquake-prone areas of the world. This type of building structure features no beams or columns but rather precast walls and slabs alone that are joined together by means of steel connectors and mortar, both of which will not necessarily prevent the formation of relative sliding between structural members when the structure is subjected to certain levels of horizontal excitation, rendering them particularly vulnerable to seismic loading. Given the scarce amount of information/data on the seismic behavior of these structures, a dynamic shake-table test was undertaken to investigate the response/performance of a full-scale two-story reinforced precast concrete wall-slab-wall structure, up to incipient/near collapse. The building mock-up was subjected to five test runs of progressively increased intensity and collapsed because of failure of the steel connectors used to join the longitudinal and transverse walls. Test data are openly available and archived at the Natural Hazards Engineering Research Infrastructure DesignSafe Data Depot.

The special dry joints for precast prestressed concrete segments are invented in this study toovercome the limitation of conventional dry joints. Eight specimens of special dry joints were madeand subjected to direct shear test. Test parameters comprise concrete compressive strength (normaland high strength concrete) and steel fiber volume added in the special dry joint (0%, 0.5%, and1.0%). Test results revealed that the inclusion of steel fibers remarkably enhanced the shear capacityand ductility index. Failure mode of specimens was changed from shearing off to concrete crackingaround shear key corners, defined as ductile shearing-off failure. Furthermore, the existing equationsfor predicting shear capacity of keyed joints were validated by the experimental results. Amongavailable equations from literatures, the Turmo’s equation yields better prediction of the shearcapacity for the special dry joint made with normal strength concrete.

Rc Columns

An analytical method is presented to estimate lateral shear strength (and identify likely mode and location of failure) in reinforced concrete (RC) cantilever columns of rectangular cross-section under combined axial force, shear force and bending moment. Change in shear capacity of concrete with flexural demand at a section is captured explicitly and the shear resistance offered by concrete estimated; this is combined with shear resistance offered by transverse and longitudinal reinforcement bars to estimate the overall shear capacity of RC columns. Shear–moment (V-M) interaction capacity diagram of an RC column, viewed alongside the demand diagram, identifies the lateral shear strength and failure mode. These analytical estimates compare well with test data of 107 RC columns published in literature; the test data corresponds to different axial loads, transverse reinforcement ratios, longitudinal reinforcement ratios, shear span to depth ratios, and loading conditions. Also, the analytical estimates are compared with those obtained using other analytical methods reported in literature; in all cases, the proposed method gives reasonable accuracy when estimating shear capacity of RC columns.  In addition, the method provides insights into the shear resistance mechanism in RC columns under the combined action of P-V-M, and it is simple to use.
