Ang mga karaniwang mahihinang parte sa isang bahay—at ang gawaing nagpapatibay sa bawat isa. Alin ang applicable ay depende sa bahay mo; lisensyadong contractor ang makukumpirma matapos tingnan nang personal.
Foundation bolting
Ano ang ginagawa nito Anchors the wooden house frame to its concrete foundation with anchor bolts so it can't slide off in a quake.
Anong mga bahay ang kailangan nito Older homes on a raised (crawl-space) foundation that were built before modern bolting was required.
Cripple-wall bracing
Ano ang ginagawa nito Adds plywood bracing to the short stud walls between the foundation and the first floor so they don't buckle.
Anong mga bahay ang kailangan nito Houses with a crawl space and unbraced 'cripple' walls — a very common weak point in older homes.
Soft-story strengthening
Ano ang ginagawa nito Reinforces a weak ground level — usually an open garage or carport under living space — with a steel frame.
Anong mga bahay ang kailangan nito Homes and small apartment buildings with a tuck-under garage or large open first floor.
Hurricane straps & roof tie-downs
Ano ang ginagawa nito Metal connectors tie the roof to the walls and the walls to the foundation so high winds can't peel them off.
Anong mga bahay ang kailangan nito Homes in hurricane, high-wind, and severe-storm zones, especially older wood-frame houses.
Chimney & water-heater bracing
Ano ang ginagawa nito Braces an unreinforced masonry chimney and straps the water heater so they don't topple or rupture a gas line.
Anong mga bahay ang kailangan nito Almost any older home — these are low-cost fixes that prevent fire, gas leaks, and falling-debris injuries.
Garage & wall reinforcement
Ano ang ginagawa nito Adds shear panels and hold-downs at weak wall lines so the structure resists side-to-side shaking and wind.
Anong mga bahay ang kailangan nito Homes with large openings, wide windows, or additions that left a wall line under-supported.
