Summaries of content, keywords and links generated by algorithms. Thank you smmry.com:
Summary 1: How to build a stair in a way which is consistent with the compressive structure of EFFICIENT STRUCTURE, without using wood or steel or concrete - GOOD MATERIALS?.
Summary 2: Within a building technology which uses compressive materials as much as possible, and excludes the use of wood, it is natural to build stairs over a vaulted void, simply to save weight and materials.
Summary 3: Build a curved diagonal vault in the same way that you build your FLOOR-CEILING VAULTS.
Summary 4: For the reasons already given in GOOD MATERIALS, precast concrete and steel are undesirable materials to use - they call for modular planning; they are unpleasant materials to touch, look at, and walk on; they are hard to work with and modify in any relaxed way, since they call for special tools.
Summary 5: Given the principles of EFFICIENT STRUCTURE, GOOD MATERIALS, and GRADUAL STIFFENING, we suggest that stairs be made like FLOOR-CEILING VAULTS - by making a half-vault, with lattice strips, burlap, resin, chickenwire, and lightweight concrete.
Summary 6: The vaulted space under the stair can be used as an ALCOVE, a CHILD CAVE, or CLOSETS BETWEEN ROOMS..
