Frame Analysis Model for RC Flat-Plate Structures under Lateral Loading |
| Abstract |
For the analysis of RC flat-plate structures, two-dimensional models are commonly used in order to calculate the lateral drift, unbalanced moment and shear at slab-column connections. However, two-dimensional models are difficult to explain the torsional behavior and load distribution under laterally eccentric loading. In this paper, a three-dimensional extended model using effective beam width concept is investigated, in a practical point of view, which is very useful. This concept employs the effective beam width coefficients and stiffness reduction factors to transform the slabs into effective beam elements. The formulas proposed previously by the authors are simplified and the analytical results are compared to other research results. Also, the stiffness reduction factors are estimated from UCB test results and suggested on the types of the slab-column connections. This article shows how to analyze RC flat-plates subjected to lateral loading. |
