## Abstract

A composite stud wall panel assembly, which can be used alone as a blast panel or as a module for wall or roof structures, comprises a frame including a plurality of spaced apart metal studs and metal crossbars interconnecting the studs; and a cementitious aggregate panel, one side of the metal studs being embedded in and permanently connected to the panel along the length of the studs.

## Claims

### Claim 1

A composite stud wall panel assembly comprising:
a frame including a plurality of spaced apart metal studs and metal crossbars interconnecting said studs at locations proximate the ends and at least one location between the ends of the studs; and
a reinforced cementitious aggregate panel, one side of the metal studs being embedded in and permanently connected to the panel along the length of the studs,
wherein said reinforced cementitious aggregate panel contains, by dry weight, 20-30% blended cement, 10-20% rubber pieces with embedded fibers; 40-60% sand and 5-15% crushed stone, wherein the rubber pieces are embedded with polymeric fibers, and
wherein the composite stud wall panel assembly is capable of withstanding an extreme loading.

### Claim 2 (depends on 1)

The composite stud wall panel assembly of claim 1 including a mesh molded into the panel at mid-depth extending between and connected to the studs.

### Claim 3 (depends on 2)

The composite stud wall panel assembly of claim 2, wherein said mesh is a metal or carbon fiber mesh.

### Claim 4 (depends on 2)

The composite stud wall panel assembly of claim 2 including shear studs connecting said mesh to the frame studs.

### Claim 5 (depends on 1)

The composite stud wall panel assembly of claim 1, wherein said frame studs are steel C-beams, and said crossbars are steel C-beams abutting or embedded in an inner side of the cementitious panel.

### Claim 6 (depends on 1)

The composite stud wall pan& assembly of claim 1, wherein said cementitious aggregate panel contains a mixture of 450 kg/m3 of cement, 272 kg/m3 of rubber pieces with embedded fibers; 877 kg/m3 of sand and 176 kg/m3 of crushed stone.
