Analysis before
assertion.

Selected public research records connected to Mantissa or authored by engineers during documented Mantissa tenures.

Engineering decisions are strongest when informed by analysis, testing and continuous technical learning.

These records are not presented as an academic CV. They show how material performance, seismic behavior and intervention in existing structures can be examined with evidence.

Rammed earth, thermal comfort and energy use

The study modelled rammed-earth external wall systems for a low-cost house in Bangladesh and compared thermal-comfort and energy-use measures across different wall thicknesses.

Mantissa connection

The published paper explicitly acknowledges support from Mantissa Design and Consultant, Dhaka.

Performance-based seismic design

The research examined a ten-storey reinforced-concrete commercial building using nonlinear pushover analysis and a performance-based design approach.

Mantissa connection

Research authored by a structural engineer during his documented Mantissa tenure.

Retrofit measures using column jacketing

The study assessed retrofit measures for existing structures, including finite-element modelling and column-jacketing interventions in a seismic context.

Mantissa connection

The conference paper identifies Mantissa-affiliated authors at the time of publication.
