“…Walls were thus modeled similarly to a plane-strain model in which length of the wall is represented by a unit-length stack of CMU blocks, as shown in Figure 1. Full details of the experimental results are given elsewhere (Dennis et al 2002;Eamon et al 2004). In general, however, the test walls had the geometry described above, were constrained at the top and bottom with side edges free (representing an in-fill wall between building columns) and exposed to a blast load with parameters described later.…”

“…Based on the impulse levels delivered to the walls and resulting wall behavior, three general blast pressure levels were specified: low, moderate, and high. From an examination of wall surface pressures taken from the experimental results (Dennis et al 2002;Eamon et al 2004), a time-varying, uniform pressure over the entire wall surface is applied for analysis.…”

However, the research of Dennis et al (2002) and Eamon et al (2004) is particularly relevant here, which concerns the specific blast loads and CMU walls considered in this study. Previous research has shown that numerous resistance parameters may affect unreinforced CMU wall behavior under blast loads.…”

“…A common existing façade for many target-prone government buildings is made of non-load bearing, unreinforced concrete masonry unit (CMU) walls infilled between building floors (Dennis et al 2002). From a life-safety point of view, the most critical concern from a lowmagnitude, personnel-delivered blast load (i.e.…”

“…Recognizing this concern, the U.S. Army Corps of Engineers (USACE) recently conducted a series of experimental tests of this construction type subjected to various blast loads to gather response data and to aid in assessing the extent of the problem (Dennis et al 2002). These results were subsequently used to develop numerical models for future studies of façade performance evaluation and retrofit options (Eamon et al 2004).…”

This study discuses the development of a procedure that can be used to assess the reliability of concrete masonry unit infill walls subjected to personnel-delivered blast loads.Consideration is given to maintain reasonable computational effort for both the structural analysis and reliability models. Blast load and wall resistance models are developed based on experimental and analytical data, and resistance is evaluated with a large strain, large displacement transient dynamic finite element analysis. A sensitivity analysis is conducted to identify significant random variables and a reliability analysis conducted with a feasible level of computational effort. Reliability indices are estimated for two wall types and three design blast load levels in terms of wall failure as well as occupant injury, over various load frequency-ofoccurrence times.---------------------1 Associate Professor,
