1. USE OF ADOBE & MASONRY

MASONRY

  • Extensively use for houses & small buildings (up 5 stories) in urban areas

  • Confining elements (RC beam, colums)

1. use of adobe & masonry

ADOBE

  • Commonly used for houses (up 5 stories) in countryside: small towns & rural areas

  • Built by the users themselves

2. STANDARDS VS. DESIGN& CONSTRUCTION

Both materials included in National Standard for Construction (RNC) as a specific codes for each material

MASONRY (NTE-E070-1982)

  • Elastic Design under service conditions

  • Provide allowable stresses values

  • New proposal: ultimate capacity approach – planning, wall density, design details for RC elements

D&C:Local goverment offices: project examination vs. actual construction up to workers or foreman as contractor. Among elder&young engineers: missunderstanding of system (RC)

2. Standards vs. Design & Construction

ADOBE (NTE-E080-1999)

  • Simple reinforcing elements are required: cane rods, wood, wire mesh or RC elements

  • Allowable stresses based on unit compression strength

D&C: design or check are rarely made. Owners construct by themselves difficult to promote use of reinforcing element if means higher cost

3. EXPERIMENTAL, ANALYTICAL & DIFUSSION WORK AT CISMID

a) Adobe walls retroffiting (Zavala&Igarashi)

at the corners of walls of existing houses using polietilene textile (bags)carrizo mat (estera)

3. Experimental.... Work at CISMID

d) Confined Masonry walls – Lateral cyclic loading(Gibu&Serida&Pique 1993) Undergraduate Civ. Eng.Thesis supported by Buckley&Konno Engs.

Different kinds of reinforcement and parameters studied (axial load, connection wall-confining column)

3. Experimental.... Work at CISMID

e) An Analytical Study of Behavior of Confined Masonry under Lateral cyclic loading (Rojas, V. 1994)

Adopting a micro-model proposed by Noguchi (1984), numerical analysis was performed using previous experimental data of tested walls. Comparison of failure pattern
