description This research presents an experimental work to investigate the structural behavior of concrete wall panels subjected to high temperature (3500c) and distributed load. Eight specimens of wall panels were tested in this study and divided equally in to four groups, each group consists of two wall panels first one with slenderness ratio (H/t=20) and the other one with slenderness ratio (H/t=14). The first group with normal strength concrete, the second with high strength concrete, the third with modified reactive powder concrete (MRPC) and the fourth with reactive powder concrete (RPC). The results shows that for wall panels with slenderness ratio H/t=20 the lateral deflection decrease by about 19% as concrete strength (fc') increase from 30.2Mpa to 69.5Mpa and about 58% as concrete strength (fc') increase to 128Mpa at failure load, while for H/t=14 the lateral deflection decrease by about 49% as concrete strength (fc') increase from 30.2Mpa to 69.5Mpa and about 28% as concrete strength (fc') increase to 128Mpa at failure load. For Wall panels with high strength concrete, MRPC, and RPC there is no big difference between lateral deflection at the linear part for panel with H/t=14and panel with H/t=20. This difference increases at the nonlinear part of the curves. The failure load increases by about 62% as the concrete strength (fc') increases from 30.2Mpa to 69.5Mpa and increases to 50% as the concrete strength (fc') increases from 69.5Mpa to 128Mpa for panels with H/t=14. The failure load increases by about 89% as concrete strength (fc') increases from 30.2Mpa to 69.5Mpa and the failure load increases by 56% as the concrete strength (fc') increases from 69.5Mpa to 128Mpa for panels with H/t=20. For all tested panels the failure mode was buckling failure and the cracks for wall panels with RPC and MRPC are close to center of the panel.
