Abstract

A monolithic reinforced concrete (RC) dense column structure includes RC dense columns along a structure perimeter, RC window structures along the structure perimeter, and a RC beam over the dense columns and the window structures around the structure perimeter. Each window structure includes RC window columns, a RC short window column between the window columns, and a RC window beam between the window columns and over the short window column. The structure further includes prefabricated wall panels having molds that casted the dense columns, the window structures, and the beam.

Claims

1. A monolithic reinforced concrete dense column structure, comprising:

one or more groups of reinforced concrete dense columns along a structure perimeter;

one or more reinforced concrete window structures along the structure perimeter, each window structure comprising;

reinforced concrete window columns;

a reinforced concrete short window column between the window columns; and

a reinforced concrete window beam between the window columns and over the short window column; and

a reinforced concrete beam over the one or more groups of dense columns and the one or more window structures along the structure perimeter.

2. The structure of claim 1, further comprising prefabricated wall panels along the structure perimeter, the prefabricated wall panels having molds that casted the one or more groups of dense columns, the one or more window structures, and the beam.

3. The structure of claim 2, wherein the prefabricated wall panels includes full-height prefabricated wall panels and less-than-full-height prefabricated wall panels fixed between the full-height prefabricated wall panels to define one or more of window and door openings.

4. The structure of claim 3, wherein the full-height prefabricated wall panels each has a window column mold at its end adjoining the less-than-full-height prefabricated wall panels, dense column molds between its two ends, and a beam mold at its top.

5. The structure of claim 4, wherein:

the window column molds of the full-height prefabricated walls each comprises a top opening and a bottom opening; and

the less-than-full-height prefabricated wall panels comprise lower and upper prefabricated wall panels, the lower prefabricated wall panel having window column molds at its two ends that open to the bottom openings of the window column molds of the adjoining full-height prefabricated walls, a short window column mold between its two ends, and a window beam mold at its top, and the upper prefabricated wall panel having a beam mold at its top and two protruding tabs that fit into the top openings of the window columns molds of the adjoining full-height prefabricated walls.

6. The structure of claim 1, further comprising:

a grid of reinforced concrete frame beams including the beam over the dense columns; and

reinforced concrete frame columns under frame beam intersections, the frame columns having a larger cross-section than the dense columns, wherein each group of dense columns is located between two frame columns and each window structure is located between two frame columns.

7. The structure of claim 6, further comprising prefabricated wall panels with molds that casted the one or more groups of dense columns, the one or more window structures, the frame beams, and the frame columns.

8. The structure of claim 7, wherein the prefabricated wall panels includes full-height prefabricated wall panels and less-than-full-height prefabricated wall panels fixed between the full-height prefabricated wall panels.

9. The structure of claim 8, wherein the full-height prefabricated wall panels each has a window column mold at its end adjoining the less-than-full-height prefabricated wall panels, dense column and frame column molds between its two ends, and a frame beam mold at its top.

10. The structure of claim 9, wherein:

the window column molds of the full-height prefabricated walls each comprises a top opening and a bottom opening; and

the less-than-full-height prefabricated wall panels comprise lower and upper prefabricated wall panels, the lower prefabricated wall panel having window column molds at its two ends that open to the bottom openings of the window column molds of the adjoining full-height prefabricated walls, a short window column mold between its two ends, and a window beam mold at its top, and the upper prefabricated wall panel having a beam mold at its top and two protruding tabs that fit into the top openings of the window columns molds of the adjoining full-height prefabricated walls.

11. The structure of claim 1, wherein the beam comprises a ring beam.

12. The structure of claim 1, further comprising:

other dense columns within the structure perimeter; and

another beam over the other dense columns within the structure perimeter.

13. The structure of claim 1, further comprising:

other beams within the structure perimeter and aligned with opposing dense columns along the structure perimeter.

14. The structure of claim 1, further comprising:

shear walls within and not along the structure perimeter.

15. The structure of claim 1, wherein the dense columns comprises a cross-section selected from the group consisting of rectangular, L-shaped, T-shaped, and cross-shaped cross-sections.

16. The structure of claim 1, wherein a window structure is located at a corner of the structure so its window columns are located on both sides of the corner and its short window column is located at the corner.

17. The structure of claim 1, wherein each window structure further comprises:

window column rebar structures for the window columns, each window column rebar structure comprising a tall rebar cage and a short rebar cage fixed to the tall rebar cage;

a short window column rebar structure for the short window column, the short window column rebar structure being between the window column rebar structures; and

a window beam rebar structure for the window beam, the window beam rebar structure being fixed at its ends to the window column rebar structures and near its middle to the short window column rebar structure.

18. A building, comprising:

first and second monolithic reinforced concrete dense column structures forming two stories of the building, each structure comprising;
